I need help.
Whenever I start up my laptop, either normally or by using safe mode, it gets a BSOD and restarts. The BSOD lasts approx 1/2 a second.

The top of the BSOD was
UNMOUNTABLE_BOOT_VOLUME

the STOP message was

*** STOP : 0x000000ED (0x8x70?900,0xCD000006,0x00000000,0x00000000)

The ? in the middle of the first parameter of the stop message was a number/letter i could not decipher. It couldve been a 0,8,or a lowercase E

Do any of you guys have any suggestions as to what to do?
Thanks for a hopefully quick and helpful response

A short, practical follow‑up with steps that help others who see the same boot-time blue screen.

As noted, a physical problem with the drive is a common cause. Before buying anything, try non-destructive repairs and data-rescue first, because continued writes can make a failing disk worse.

From a Windows recovery environment, attempt a filesystem repair (this often fixes a corrupted NTFS metadata and will try to recover readable data):

chkdsk C: /r

Let it finish; it can take hours on large or damaged disks. If chkdsk hangs or reports many bad sectors, stop further write-heavy operations and image the disk instead.

If the drive is unstable, attach it to a second machine (USB-SATA/IDE adapter or external enclosure) and make a sector‑level image before trying more fixes. On Linux, GNU ddrescue is commonly used; a two-pass workflow looks like:

ddrescue -n /dev/sdX drive-image.img rescue.log
ddrescue -d -r3 /dev/sdX drive-image.img rescue.log

The image protects remaining data and lets recovery tools run against a copy. After imaging, use recovery tools (partition recovery or file recovery such as TestDisk/PhotoRec) on the image rather than the original.

If data is critical and the disk shows mechanical failure (clicking, extreme heat, SMART reporting reallocated sectors), stop DIY attempts and consult a professional recovery service—imaging or aggressive fixes can destroy chances of successful recovery.

Finally, once data is safe, replace the drive, install a fresh OS, and restore from backup. For prevention, enable SMART monitoring and keep regular backups so a single disk failure does not become a catastrophe.

First thing I would check is to make sure the HD is properly seated in the laptop.

Pretty sure it is. I'm assuming the HD overheated recently. In this case, what would I do?

If the HD overheated chances are it is fried and will need to be replaced. - You can boot a windows install CD and check to see if you can access the drive using the Windows recovery option.

I should also mention that most of the HD vendors provide utilities that can be down loaded from their sites to verify the health of the drive. For instance IBM Hitachi Drive Fitness Test (DFT) http://www.softpedia.com/get/System/Hard-Disk-Utils/IBM-Hitachi-Drive-Fitness-Test.shtml is a tool I keep around for this very purpose. Check with the vendor of the HD to see if they have similar utilities. I know Western Digital and Maxtor have similar utilities.

ya, the HD is completely fried. Guess that was the problem, thanks for your help!
