I dual booted my computer which originally had Windows 7 installed on it, with Backtrack 5 R3. I went through the install process perfectly and BT was working very well.
I then restarted my system and booted up into Windows. I went into disk management, because I was curious about what partition BT was installed on, and by mistake I deleted the partition that it was installed on.
I thought there was nothing on this partition and was really stupid not to check how much space had been used on the drive. Anyways, I restarted my computer and came up to the screen that says:
"error: unknown file system Grub rescue>!!!!!!
This is EASY to fix, I had it once before with Linux Mint. I just repaired the boot loader with my Windows 7 Recovery Disk. However, this time it is not as simple. I cant boot into ANY CDs/DVDs, including my Windows 7 disk and backtrack, even though my first boot device is set to Internal CD ROM.
The problem is that when I boot up my computer, I cannot access my BIOS. No onscreen keys r shown (the usual F2 on my LG laptop). I have tried all key combinations incase it had switched my BIOS key, which is very unlikely, but it was worth a shot. It just takes me straight to the GRUB rescue prompt where I can virtually do nothing. I,ve tried LS at the rescue and tried to boot up into one of the hard disks, help commands and any other obvious commands that I thought might work, but nothing!
I cant remember off-hand all the model numbers, but my laptop is an LG , as I mentioned above and have a Toshiba HDD.
Anything else you need to know ?
How can I fix this ?
