o i recently installed ubuntu linux operating system over my windows xp . now wheen i boot into ubuntu it doesnt let me there is an black screen with an error message which has a couple of numbers,in a bracket then kernal panic then some more numbers then timer not working debug and send error report then try and boot with the nopic option. i cant even acces,my hidden partiton in to do a pc recovery and bring back to windows xp.
The usual answer to this is to use fdsk to remove all partitions on the drive, make a new partition and reinstall XP from a CD.
However if you use fdsk it will delete the recovery partition.
To recover HP/Compaq laptops. 1. Reboot, and repeatedly press F10 at the HP logo until the recovery screen appears. 2. When the recovery screen appears, press "Next" and then "Yes" to perform a non-destructive recovery. 3. To perform a destructive recovery, click "Advanced" and then "Yes". 4. After the recovery is finished, the laptop will reboot.
