Hey guys I'm new here as well as to linux so pls bear with me.

I got following situation:
I had Windows XP installed on my Laptop
I also had Linux Mint 6 installed on my Laptop

So at one point I decided to update my Linux Mint to a newer version. I download the .iso burn it to a disc and put that disc into my Laptop.
During the installation however my CD drive decides to give up on me and the whole thing freezes. I try to boot but I get a grub rescue> message with no available commands whatsoever. I got an USB stick with Puppy Linux working on my Laptop again but I cant get into Windows XP because of the grub error.

So the problem is that I want to be able to access Windows XP again (As well as the installation of Puppy Linux on my HD) BUT my CD drive is broken.
Any ideas whatsoever?

Thanks in advance

Either the boot partition or the grub files have become corrupted. If you have the XP install CD you can repair the MBR via the fixmbr utility.

Yes I knew that already. However that was not possible because of the broken CD drive, Thanks michaelk nonetheless.

However I was able to fix this on my own for people with a similar problem I will post the things I have done:

I downloaded puppy and installed it on an USB-stick
Booted into Puppy on my Laptop and went into Menu > System > Grub Loader configuration (or something similar I can't recall the correct name right now)
Installed a new Grub Loader (important you have to install to MBR)

Now I can boot into Windows XP again and am currently downloading the newest Linux Mint again to install that one on a USB stick as well and eventually install it on my Laptop again! Man I missed my little Penguin
