I have an old system with P4 processor, 1.12gb ram, 40 gb hdd (of which maybe 10 gb is in bad sectors) which was running Windows XP. I wanted to experiment with it. So, I installed Ubuntu 13.04 on it and completely removed windows xp. According to the system requirements page of Ubuntu, I gather it must be able to work perfectly well.
It installed without problems. When I try to boot the pc, I get an error like this
error:attempt to read or write outside of disk hd0
grub rescue>
Please help. I am a complete beginner with Ubuntu. Thanks in advance!
