well i got a computer with some problems..

i got the pictures from the hard drive and then decided to format it..
as it didn't seem to start the setup on that pc, i put the hard drive into my computer and formatted it in there..
but now as i wanted to put the hard drive back where it belongs, the pc says something like this:

"Invalid BOOT diskette.
Please insert valid BOOT diskette in A:"

i tryed to change the boot device to cd rom, IDD, and disabled, but it still wants its boot diskette..
and i tryed to disconnect the diskette reader but nothing..
but it works on my PC..

but when i put the windows xp cd in it, the setup started and i thought about repairing the windows, but i thought maybe someone could give me an advice to get over that problem more easily..

Well...I guess I don't understand.

The XP CD formats, no need for a boot disk at all.

I would:

a. Make certain that the BIOS primary boot option reflects "optical drive", "CD/DVD", whatever my BIOS reads that will enable a boot from CD.

b. I would delete all existing partitions, once XP started to launch the install process.

c. I would create my new partition for XP (which XP will format) and allow the install to proceed.

The one other thing I would check...is that the BIOS recognizes the drives which are actually installed on the system (first screen).

When you changed the boot order in the BIOS to have the CD first, did you "save changes on exit"?

i have already formatted that hard drive.
but i did it on my pc and there it works just fine..
but when i put it into that computer where it was before, it needs a boot diskette..
and yes, i tryed to change the order, disable all, change between different boot devices (IDD/CD ROM/CD ROM&IDD)
and as i already said, i even disconnected the floppy reader and disabled it from Setup..

and of course i have saved these settings..

it's always the same except when i inserted XP cd..then the windows setup started, but i thought maybe there is some easier way than repair or format it again..

What I suspect is happening is that the BIOS is confused. It can't find a boot device so it "defaults" to the floppy (probably a built in routine that's not listed in the BIOS).

When you insert a bootable CD it merrily chugs away - happy that it found some bootable media.

What I suspect has happened is that formatting the disk on your PC did not install a boot sector on the hard drive - so it can't boot from it. I also suspect that you've got a copy of Windows on this hard disk that you want to boot from - and if that's the case, then the repair installation is the only route that I know of to attempt to fix it.

You may be able to "fix" it through the Recovery Console - but if my suppositions are correct there'll be more issues later on.

Here's a couple of articles about these situations:

My browser caused a flood of traffic, sio my IP address was banned. Hope to fix it soon. Will get back to posting as soon as Im able.
