Installing XP after Win 7...

Stoned Bob · Oct 2, 2009, 10:19 AM

I'm trying to install XP on d: and I have Win 7 installed on c: but after copying the files in the setup of xp I get this message "Error loading operating system".
Now I cant boot anything anymore

.

I tried to use the boot repair option of the Win7 cd but that didn't help.
Then I tried the g:\boot\bootsect.exe /nt52 ALL command(read this could help somewhere) but this didn't help either.
Running xp setup again doesn't help either.

So now I'm stuck with no OS at all

.
Any ideas?

I tried doing this. It was a royal pain in the ass, lots of googling involved.. and even then it didn't seem to work right. Most suggestions didn't work like explained.

I ended up formatting and installing XP first then Windows 7.

That shouldn't have happened, the XP bootloader should have just overwritten the Vista/Win7 bootloader. I've done this a bunch of times with XP/Vista. Hmmmmm, sounds like you might be screwed. You could try installing Win7 over top of Win7 (Windows installer backups up the contents of the entire partition into a folder called windows.old).

Once you get into Win7 you can then use EasyBCD to add Win XP to the bootloader and have it rewrite the MBR.

^ Does not work the way you say it does.

Maybe with Vista it did, but 7 changed things. Forever.

Yes, I did the BCD edit via command prompt, the program. I tried dozens of things. It simply vanishes.

Best and easiest way to fix it is format, install XP first, then install Windows 7.

I've reinstalled Windows 7 on my laptop because I ****ed it up 6 times now, and everytime the installer finds Windows already installed and backs it up. This is with RC1, RTM and Dell OEM

Perky McGiggles · Oct 2, 2009, 07:46 PM

Yeah, you've reinstalled windows 7 on a machine with XP already on it. The problem is installing XP AFTER Windows 7 is installed.

Try it, tell me how you did it and I'll see if I can repeat the process.

AluminumHaste · Oct 2, 2009, 07:51 PM

lol no thanks

Have you tried reinstalling the MBR from the Windows 7 installation medium? The boot repair in Windows 7/Vista doesn't seem to try that when I overwrote the MBR on a machine with grub accidentally.... It seems that installing XP after 7 or Vista seems to overwrite the bootsector as well. Here are the respective commands.

bootrec /fixboot
bootrec /fixmbr

Where I got the commands.

Yup tried that as well.
I guess Ill just remove win 7 and install xp first, the installation was only a few days old so its not so bad.

This is strange, now the harddrive stops the pc from booting... it just stops after detecting in the post.
Tried it on 3 different computers and all hang after detecting it.

Its a maxtor diamondmax plus 9 120gb sata disk.
And its not trying to boot from it.

Perky McGiggles · Oct 3, 2009, 04:18 PM

That is odd, can you test it on another drive? Sounds like it might be more hardware related than Windows.

Another option is try resetting the bios. Something funky might have happened where the drive isn't be recognized as it should.

[email protected] · Oct 3, 2009, 10:32 PM

it sounds as though the XP install marked the D partition/drive as Active (thus disabling the Vista/W7 partition/bootloader). use DiskPart and check which drives/partitions are active. I think this is the reason why it is recommended that XP is installed the the C partition then Vista/W7 gets installed afterwards. Another option is to run a WinPE environment and use BCD edit to mark the W7 install as default, removing XP, then when in W7 re-edit BCD entry finding XP install and adding to boot option.

Best of luck

I have xp installed on another 80gb drive now but the 120gb drive it still broken

.
I tried resetting the bios but it happens on 2 other computers which work perfectly fine.
Maybe the hdd was allready dieing...

Sounds like the HD is dead. If its not detected in BIOS then it was hardware failure giving you issues.

Stoned Bob · Oct 4, 2009, 01:54 PM

Well its detected but the system halts after that.
