vista tries to boot into xp instead

[kangarulzx]

i got vista installed in AHCI sata mode
i got xp installed in IDLE sata mode

when i tried to boot up vista, it tries to boot up xp instead and bsod occured.
i used vista eRecovery i typed bootrec.exe /fixboot and it didnt work it still tries to boot into xp, i typed bootrec /scanos , it only scanned my D:\Windows XP OS only

what should i do to boot back my vista? im using acer 8930g model

i used vista dvd and started the repair, it didnt work, its still tries to boot into xp and recieves bsod

at first there were no os for me to select , and yes i have vista and used it before

and the unkown on unkown local disk

i am running this on AHCI sata mode

extra: ive taken this pc to acer to fully recover my pc before because i messed up my dual boot and i cant boot on either Vista and XP.

ive got the laptop back with everything installed the way it were when i first bought the laptop

after 2 weeks of using it (i didnt attempt on installing xp or anything) it shows NTLDR is missing when i start up, i used the vista dvd to "startup repair" when i reboot i by passed the NTLDR is missing and saw the xp logo (??the laptop is new i dont know why it shows the os before) and bluescreen occured after that and restarted.

thats why i installed xp on IDLE after that occurred to find help

This is from my VistaBootPRO (i opened it on XP)

There is currently 1 OS(s) installed on your system.
The current boot timeout is: 5
Default OS: Windows Vista
Entry 1
----------------------------------------------------------------------------
Name: Windows Vista
BCD ID: {default}
Boot Drive: unknown
Windows Drive: unknown
System Bootloader: \Windows\system32\winload.exe
Windows Directory: \Windows

do i go to: Select Window Vista -> Advance settings ->Debug the boot process -> apply settings? (im doing this all in xp)

Hi ,

Not sure I follow the sequence of events.

You had XP first, then installed Vista.

It was OK for a while, then you got NTLDR is missing, so you reinstalled XP on a different drive ?

Quickest solution is to use the Vista dvd to reinstall Vista on the partition it is now on.

http://www.vistax64.com/tutorials/117366-clean-install-full-version-vista.html

It should recognise the XP install and list it as Legacy o/s in the boot menu.

You should then be able to boot into Vista.

If you get the NTLDR is missing and can't boot into XP, try this:

Boot into Vista, see what XP partition drive letter is.

If it hasn't got one, go to Disk Management and assign your XP drive a drive letter e.g. D. Then exit Disk Management.

Open an elevated Command Prompt ( rt click and run as administrator)

At the prompt, type : ( press Enter after each command )

bcdedit /create {ntldr} /d "Windows XP " {enter}

bcdedit /set {ntldr} device partition=d {enter}

bcdedit /set {ntldr} path \ntldr {enter}

bcdedit /displayorder {ntldr} /addlast

Close the command prompt and restart.

Hope it helps

First of all dump VistaBootPro since that's a rippoff of another free BCD editing tool called EasyBCD from Download EasyBCD 1.7.2 - NeoSmart Technologies I ran into VistaBootPro just before learning what that was when coming across EasyBCD that sees an active support.

Besides all that the thing that would help here is what is being seen in the BSODs that come up. It sounds like you installed XP after Vista on a second primary but used the wrong tool to edit and backup the Vista BCD file. Now it will need to be rebuilt.

The first step takes you to the command prompt option when booting with the Vista dvd. When going into the repair tools you select that option not the startup repair. The following commands are then used to hopefully see you back running rather quickly.

At the command prompt since the detection of the original installation won't be automatic would be to type in the "bootrec /scanos" command and allow the Vista installation to be detected and presented. When displayed you type Y for yes to see the message "sucessfully added" where you can then proceed to enter the "bootrec /rebuild bcd" command at the prompt.

The tool there has been told that the Vista installation is the one needing the repair by the confirmation method. The next commands used would be for when not seeing the BCD rebuilt on the MS page at How to use the Bootrec.exe tool in the Windows Recovery Environment to troubleshoot and repair startup issues in Windows Vista

sorry i didnt type it specifically

vista is Pre-installed on my laptop (installed in AHCI sata mode)

after a few weeks of using (i didnt attempt on installing ANYTHING to do with OS, when i open my laptop, it suddenly shows NTLDR is missing

it was wierd because i have taken my laptop to the Acer Company to completely Reformat my Drives and i know that Vista doesnt need NTLDR to boot

ive used the Vista DVD recovery CD to run "Startup Repair"

restarted the computer it bypassed the part saying "NTLDR is missing"

saw the Window XP loading Screen (!!?? It was wierd because ive taken my pc to Acer to fix it and my drives are completely empty, just as new as the time when i first bought it) and immediately after that bsod occured because AHCI does not support old version OS

Right after not able to log into my Vista OS, i changed my SATA mode to IDLE and Installed XP on IDLE to find solutions to this problem

The reason why i took my PC to Acer Company to reformat in the first place is because i messed up the dual boot and i cannot boot into Vista and XP

 

[kangarulzx]

this is what happened when i type bootrec /scanos , total identified window installed : 1

but i have Vista Pre Installed (in AHCI) and XP installed (IDLE)

I dont think my laptop knows that my Vista Exists, Its Boosting XP instead of Vista in AHCI sata mode and keeps recieving bsod and restarts computer automatically since AHCI doesnt support XP / older os versions, Vista is Preinstalled and i dont know why XP tries to Boot up instead.

Im right now on IDLE sata mode boosting XP to reply on this forum

Enabling AHCI in a system's BIOS will cause a 0x7B Blue Screen of Death STOP error (INACCESSIBLE_BOOT_DEVICE) on installations of Windows XP and Windows Vista where AHCI/RAID drivers for that system's chipset are not installed; i.e., boot failure.[5] Switching the chipset to AHCI mode involves changing the BIOS settings and will not work. Usually, manual installation of new drivers is required before enabling AHCI in BIOS.[6] Alternatively, a "Repair" installation with the appropriate driver loaded during the setup process usually corrects the problem. Advanced Host Controller Interface - Wikipedia, the free encyclopedia

And that's right out of wikipedia there. The only thing is that Vista doesn't see the same type of repair install option where everything remains intact simply replacing the basics and rewritting boot information without wiping the registry and all programs on. Apparently the method of dual mode settings for dual booting is how you ended up in the tuff spot between a hard place.

Before heeding SIW2's adivce there your last option would seem to be "Step Four: Nuclear Holocaust" seen at Recovering the Vista Bootloader from the DVD - NeoSmart Technologies Wiki

I just bailed someone else out pointing them there for a slightly different problem while that's the last ditch repair option available when things get trashed prior to seeing a full reinstall of Vista.

night hawk i think ill take my laptop to acer's again... couldnt seem to get anything to work

 

[kangarulzx]

when i type

bootrec.exe /rebuildbcd and pressed y , it says denied (or something like that)

i cannot even use my vista DVD to reformat the whole thing

 

[Night Hawk]

You typed the command wrong. When at the command prompt when booting the VIsta dvd you don't add the .exe extension onto bootrec /fixboot or bootrec /fixmbr commands. The bootrec /scanos and press Y for yes once the Vista installation is detected should see the successfully added message where you can then use the other commands.

Once you get past the Install Now screen to proceed with the installation you should see the "drive tools" section where the option to reformat is seen there. If you continue to run into access denied errors if XP or Vista was originally preinstalled a 3rd party drive tool should easily get you past that.

GParted live can easily see the Vista primary reformatted or deleted entirely for a new one for Vista to go on. If the Vista dvd is branded recovery disk that would be an option for that. If you don't get any further with the Vista dvd then grab the free tool from SourceForge.net: GParted: Files

 

[SIW2]

Hi kangarulz,

In addition to Night Hawk's advice

If you want to delete everything,

Boot the dvd to command prompt, as before, type

X:\sources>DISKPART {enter}

Microsoft DiskPart version 6.0.6001
Copyright (C) 1999-2007 Microsoft Corporation.
On computer: PC-PC

DISKPART> SELECT DISK 0 {enter}

Disk 0 is now the selected disk.

DISKPART> CLEAN ALL {enter}

DISKPART> EXIT {enter}

Leaving DiskPart...

Hope it helps

That will work too!

The preference here for GParted is simply due to custom booting a distro or two at times along with XP, Vista, and now 7 betas added to the mix. I've never lost a primary when going to resize one with the Linux drive tool.

Your main concern there however is seeing the drive cleaned up for working install to take place.

When adding XP into the mix there you immediately trashed the Vista mbr where the startup repair tool is used to restore that unless you unplug the Vista drive for a stand alone install of XP on a second drive. Then you simply edit the Vista BCD as well as copy the XP boot files over to Vista's root.

The ntldr file missing error comes into play usually when the entry in the boot.ini file is not corrected to point the Vista boot loader to the correct drive or partition where XP was installed to along with having XP set as the default OS. It gets more touchy when one of the versions is already a factory preinstall over simply setting up a dual boot on your own.

Once you have the factory install of Vista restored and running then you can consider using a boot loader editor to see XP added back in there without trashing the new mbr entries.

Hi,

I'm a fan of GParted , too - always useful to have.

The latest stable builds have been long awaited. With the older 0.3.xx releases you were stuck at the 1024x768 default resolution despite having a widescreen display. If you brought it upto 1280x1024 half the stuff moved off of the screen when reaching the main gui. Not good!

The releases that followed had that "start x" crap that often crashed when unable to detect the monitor you were using. The new builds out lately automatically detect your monitor's native resolution and adjust to that instead of seeing a "strike three you're out of there!". Plus!

The partitioning, formatting or reformatting even goes well. I've never lost any primary I shrunk down and even expanded back later with it. That comes in quite useful for predetermining your partitioning for dual and multibooting versions and other OSs making it a choice option. :D

hey SIW2 , wouldnt the DISKPART>CLEAN ALL delete every os on my hard drives including my XP os?

im really confused im not really a good understander

is there a way to make my Vista Boost Up instead of deleting everything? because the problem sounded pretty easy that my MBR is somehow overwritten by XP os.

its wierd that Vista DVD Doesnt Work For me at all which drives me insane, the AutoRepair Command, doesnt help.

sorry im going to try repair this ill post more photos (from my camera) and see if you guys can help me find the best solution for this problem.

thanks

 

[kangarulzx]

i clicked on the diagnostic tool, error just comes up

Yes, that would be if you wanted to start afresh and reinstall Vista from your dvd/recovery dvd.

Since XP was installed on an ide drive last? and Vista first? by your description onto a separate sata the quesion now would be if you had both drives plugged in through all that. If the ide wasn't plugged in when installing Vista the boot information is on the sata while the default boot device is the ide drive.

With the Vista boot information on the sata the startup repair wouldn't seem to work if the XP ide drive is set as the boot drive in the bios. The system will continue to look at the XP mbr information there.

The best method when dual booting across drives is to have the second drive unplugged while one version goes on the other making that bootable. Once both versions are installed separately you simply set the Vista drive as the default boot device and edit the boot loader there to see XP added in.

Hello Night Hawk, im going to explain from the beginning again please take the time to read.

ive bought my laptop, vista pre-installed in my ahci

ive installed xp in IDE

Ive somehow corrupted the files, and unable to boot into vista nor xp

ive taken my laptop back to acer to get it fixed

acer deleted everything on my laptop and re-installed it with vista again

after 2 weeks of using, suddenly it showed NTLDR is missing in ahci

i placed the vista dvd into my drive and pressed startup repair

it bypassed the screen ntldr is missing but it then tries to log into window XP

window xp cant be in my computer because i didnt install it when i recieve my laptop back from acer

what do i do to log back into vista?

 

[Night Hawk]

The first thing needed here is knowing if you left the ide in when sending the laptop back to Acer? Did they end up installing Vista over XP on the ide or somehow see XP boot information added in when reinstalling Vista on the sata?

If the ide drive was left in that would account for why you are seeing XP boot errors at this time. The first thing there would be removing the ide drive if that's still in the laptop and booting from the recovery disk if you have one. If not you can download the 120mb recovery disk image containing the repair tools from Windows Vista Recovery Disc Download — The NeoSmart Files

When booting from the cd-r you burn from that the install now option link is seen but unusable since this only contains the repair tools section. At the command prompt option you would need to type bootrec /scanos in order to have the Vista installation discovered and displayed.

If displayed right away simply press Y to answer yes and then proceed to use the "bootrec /rebuildbcd", "bootrec /fixboot", and "bootrec /fixmbr" commands at the prompt there. That should see the Vista boot information rewritten without seeing any more XP boot errors coming up on you.

The last step is creating a set of recovery disks from the recovery partition and seeing Vista installed all over again without the ide drive present. But you will want to try the manual repair method first if possible. How to use the Bootrec.exe tool in the Windows Recovery Environment to troubleshoot and repair startup issues in Windows Vista

Hello Night Hawk, ive done exactly as you have asked for and ive burnt the iso on a disk.

this is what happened in the process, ive taken pictures instead for easy reference

access denied after typing yes from the command, recboot /rebuild bcd , but the other commands can be successfully entered

restarted

xp logo appeared and right after that (without loading) bluescreen appeared and immediately restarted pc.

i still couldnt boot into vista, im doing this in AHCI sata mode
what should i do now? thanks
