Having trouble installing a piece of hardware? Want to know if that peripheral is compatible with Linux?

i rebooted my desktop computer last night after attempting to install windows XP on another partition, xp made me restart and now the drive stops my machine from getting past POST, when i unplug the drive i can boot into a live CD, but if i try to hotplug the drive i get nothing, can someone please tell me how to recover the MBR of this disk so that i can use it again?
How do you have the hdd configured in the BIOS? Do you see it while in the BIOS? Just curious as to how you have things configured in the BIOS? How do you have your drive configured in the BIOS with type and what about AHCI? Tried Legacy?
I thought your statement about the POST was that the system was failing. So the machine just doesn't detect it.
Which Livecd? What about passing parameters to the kernel at boot?
the machine detects it at post and hangs, it's an ubuntu 9.04 live cd, the drive is configured to S-ATA/P-ATA mode so that the bios prefers sata over pata, other options are PATA and SATA, i can only boot the machine past post if the drive is disconnected or sata mode is disabled
I would try to burn a copy of PartedMagic 4.4 to see if it boots with the HDD present. PM 4.4 has Super Grub Disk for repair as a boot option . You might also try the latest SystemRescueCD.
I would also look to the interplay of the BIOS settings and how you have configured the HDD. As onebuck intimates, you can use the BIOS alternatives IDE/SATA/AHCI and the set-up configuration of the HDD to try to get the BIOS to co-operate with a live-cd to find the HDD. It is not supposed to disappear.
An advantage of using PartedMagic or SystemRescue is that, while playing with the BIOS and the HDD jumpers, you can use cheat codes to give yourself added variations, if that helps.
If I couldn't get either PM or SystemR to boot, I would try to set the BIOS to Fail-Safe Defaults and try again, changing the HDD to follow BIOS setting given under Fail-Safe.
I would be useful if you followed the querying admonition of the wise onebuck and supplied much more detailed information.

Depending on the motherboard chipset, you may have a motherboard that is sataI and a drive that is sataII. Most of the sataII drives have a jumper to set the drive to sataI. I have seen several Seagate drives behave similarly.
If you want more advice on your problem, you need to tell us what are your equipment specifications and settings, what you tried, and what the result were.
If you are not more perseverant, neither you nor we will make much progress. onebuck had many useful suggestion for ways forward; try some.
In practice, I would pull the HDD so I could get into Setup and start to experiment with the BIOS, reinstalling the HDD to see if it is recognized by a live-cd. The HDD was recognized before, it should be again. However, there are several variables. Why it isn't is a bit of a mystery. There is no standard answer.
