'Error Loading Operating System' When booting BT4

[LuCiEN]

Hi

I have 2 hard drives on my machine, one with BT4 and the other was empty, until recently decided to put windows on it, so, I unplugged the first hard drive (the one with BT4 on it) and set the empty drive as the first HDD, after successfully installing and booting windows on the empty drive, I plugged in the BT4 HDD (as the first HDD now) and got the error 'Error Loading Operating System'.
I tried booting into an ubuntu live CD (just one I had on hand) and can see all the files on the filesystem for backtrack (Except the files in root?)

I'm not sure what to do? Any advice?

Is it your BIOS that is giving that error? If so you probably need to use a boot CD to play around with your partition table, you might need to set the master boot record and also set the boot flag on the appropriate partition.

Hi

This is my the current partition settings:

Also, not sure if this is of any importance, but when I tried to boot the backtrack live CD, I got the error:

Kernel Panic
Not Syncing: VFS: Unable to mount root FS on unknown-block(hd0,0)

Also, normally when I'm booting off grub, the command is:
kernel (hd0,0)/vmlinuz root=/dev/sda3

Thanks

EDIT: Have decided might as well just go to BT4-PreFinal, but is there any way I can retrieve the files contained in the root folder? For some reason I cannot see them using the live cd (Can see the folder and go inside it, but cannot see any files present)

EDIT2: Sorry, have just realized that this is in the wrong section, I'm using BT4-Beta, feel free to move the thread.

EDIT3: Just did enable show hidden folders in /root and there's 3 files in there? Not sure what that means. [Files are: .wapi, .bashrc and .profile.

Also could it be anything to do with bootloader[s]?
In the /boot folder I have:
abi-2.6.22-14-generic
config-2.6.22-14-generic
initrd.img-2.6.22-14-generic.bak
memtest86+.bin
System.map-2.6.22-14-generic
vmlinuz-2.5.22-14-generic

Sorry,

Have just booted it into BT4, but still no files? I cannot see any of my original files that resided in root, also some of the software I installed is not present.

Any way to recover the data?

Thanks
