I got a copy of Mandrake 10.1 so I could learn Linux on an old desktop. I partitioned the hard drive and the install seemed to work.
After the reboot, the bootloader loads and I see many prompts (everything says OK) and then....a blank screen. That's it, nothing else.

I tried CRTL F1, and nothing happened.
I pressed ESC at the bootloader and tried two commands I was asked to try (by Mandrake support)

1)linux noapic acpi=off
The first command still led to the blank screen.

2)linux nolapic noapic acpi=off
The second command hangs at the step "Calibrating Delay loop"

The PC is a PIII, 128Mb Ram with a maxtor hard drive and a NVIDIA card. I tried several reinstalls with several configurations. Only the Intel graphics card, both graphics cards, the other option (can't remember it now) and nothing seems to work.

Windows still boots perfectly.

Anyone have any ideas?

Try to boot in failsafe mode. If booted then set default run-level to 3 and reboot.

If you are able to do so then possibly you have incorrect monitor settings.

Please do it, and get back, soon!

I did it! Thanks for the help. I had the wrong xserver selected.
