Windows 7: Laptop turned off during SP update now blinking cursor on boot.

You may need to do this if you confirm the HD is bad: e.g. won't be detected in BIOS setup even after reseating firmly and checking any cabling, won't be detected by HD Diagnostic when booted in either PC with all other HD's unplugged. An alternative diagnostics is Partition Wizard bootable HD surface test .

If you have another HD it should work in the problem PC so try the steps to reset BIOS and make sure you're correctly booting DVD. Remember you can wipe the HD first to force the installer to auto-start install.

Only as a last resort do I install in another PC since it normally takes adapting the install to boot on different hardware. This can be done with SysPrep to move HD to another computer or Paragon Adaptive REstore CD freeware which I can provide a link for if needed.

tried paragon, burned the dvd but it won't boot. Set bios to only boot from optical and took out the HDD and it just says "unable to boot from any device" "no valid OS"

Did you reset the BIOS to defaults? Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS

Is the HD still not detected anywhere in BIOS setup?

Reset bios to default, yep. The hard drive has always been recognized by the bios. I took the hard drive out and plugged it into an external enclosure to see if the Dell desktop could see it and it did. Ran paragon on that computer and all was well, but I think it only sees IDE and sata drives not USB so I couldn't really do anything. Is there a program similar that can see sub drives and maybe fix the mbr? I almost feel like that's what it could be.

what's also odd, you mentioned that it would force you to install an OS if you have a blank hard drive in there. When I throw the good hard drive that has been formatted in the thinkpad, i get the same result..blinking cursor.

Try removing the formatting from the blank formatted HDD with Diskpart Clean Command to see how the problem laptop reacts when you try to boot the installer.

See if you can boot a flash stick formatted with the Windows 7 installer for your version from Steps 1 and 2 in Clean Reinstall - Factory OEM Windows 7.

Reset the BIOS to defaults again, set HDD to boot first, use the HP ESC or F9 key to trigger stick. Try also booting a disk this way.

You should be able to copy out files via explorer from the HD mounted in external enclosure, run the maker's HD Diagnostic Windows full scan, check the file System using Disk Check or Partition Wizard Check File System .

All fixed. Was able to boot from an external dvd drive, so I booted up with a windows 7 disk in there and clean installed.

Thanks for all the help guys, made things easy.
