I tried reinstalling my pal's PC but when the Windows CD formatted the HDD
and started copying new files and reached 45% of the process the PC restarted saying NTLDR is missing.
I've reinstalled PCs millions of times and that's the first time I see
this kind of error. Is that a hardware problem or what? The boot order in BIOS is CDROM for 1st and HDD for second boot device.
