I'm going to be crazy with my laptop. Yeah, is quite old but rock solid and quite fast running XP when it boots.
Yes, the problem is *when* it boots.
If the system is cold, after the BIOS messages it stops regularly with the error 'Impossible to find a disk. Insert one and press CTRL+ALT+CANC to rebot'
The BIOS detects the hard disk, and I also tried to replace it with another one but nothing changes, so I guess the issue doesn't depends from the disk.
If an external sw accesses to the disk prior the boot, it works perfectly, as if I boot from Hiren's Boot CD firts, then I choose one of the Hard Disk Tools i.e. the S.M.A.R.T. detection: after a reboot the system loads and XP is stable until its shutdown.
No way to start XP if simply start Hiren's Boot CD then reboot the laptop without accessing to the disk.
I have inspected the mother board for defective CAPS or cold solders, but everything looks fine to me, in fact when XP has been successfully loaded, is perfect for weeks if no powerdown occurs.
What can I check more?
Thanks for your help here
