I've an old PC, which was used in dual-Boot with Linux Mint. I removed the Linux Mint partitions and an old data partition and enlarged the Windows XP partition. After starting, I got the grub not there (or the like) message.

Then I tried to started from the Windows XP install-CD to use the rescue mode to fix the MBR, but it crashes (something with PCI.SYS). I tried testdisk and it started to boot. I was relieved, but then.. it just restarted.

I've no idea what to do, to get this machine working again. If you need any information leave a comment.

At which point exactly does the crash occur? If you cannot boot from the XP CD at all, restoring or clearing the MBR using a Linux LiveCD should help (the XP CD should boot after that), but be extremely careful with dd and the like and don't specify the wrong device by mistake! – Karan Mar 11 '13 at 0:43

You should reinstall your entire operating system as it might not be repairable with the Windows XP disk anymore.

Just use the disk to reinstall the OS.

Especially if it's an old system- it's likely a clean install will improve performance quite significantly. – Austin ''Danger'' Powers Mar 10 '13 at 16:02
The problem is that the CD crashes with a bluescreen and some address after 'PCI.SYS' (something like this: so I might not even be able to re-install it. – Joschua Mar 11 '13 at 20:48
Why not install a different OS. Like Linux(Ubuntu). Just get on a working computer and download it. – user201825 Mar 27 '13 at 13:45

Re-installing Windows from scratch will be the most sure-fire way of restoring your Windows bootloader. However if you want to try recovering your system, follow these instructions from

Method 2: Use a Windows XP installation CD/DVD

Grab a Windows XP installation CD and boot from the CD with the hard drive attached and select the “Repair” (choose “R”) option when it is presented to you. After that you will taken a common prompt. Once you get to the command prompt give the following command after selecting “1″ for :

1) C:\WINDOWS and now type the following commands:

C:\> BOOTCFG /rebuild

The last command (BOOTCFG) will rebuild your boot.ini as per your hard drive partition table and will put appropriate entries for Windows XP. Also this command will most likley add a new entry to your Windows XP boot menu. You can easily delete the old entry by modifying the C:\boot.ini file once you successfully boot into Windows using the newly created entry.

Note: You will need to know the “Administrator” password before you can enter into the command prompt. If you don’t have one, just press “Enter” key.
