I have what I think is a usual “Invalid partition table” problem.

The other day we had a “power glitch”.  When I rebooted after it…I got “invalid partition table” after the boot screen. The next day I borrowed a friend’s machine and looked it up. What I found said unplug all USB devices (except mouse and keyboard).

 Then reboot when the boot screen finishes press f8 and get to the recovery menu.

 I did that. However I was not quick enough to press f8 instead of recovery menu I got system information. Then it booted into Windows with no problems.

With further investigation I discovered that it would boot into windows as long as the USB devices were unplugged. But once windows started I could plug the devices back in with no porblem

I know this is not normal but my question is is the problem in the HD or the US drives

Try resetting BIOS to Default settings, may help.

 

Turn on the computer.

  • When the first screen displays,  do one of the following to see which gets into BIOS setup
  • Immediately press the F10 key repeatedly, about once every second, until the BIOS Setup program opens. 
  • OR> Immediately press the Escape key repeatedly, about once every second, until the Startup menu opens. Then press F10 to open the BIOS Setup program.
  • In the BIOS Setup utility, select the File tab.
  • Select Apply Defaults and Exit .

that did not do it so I did some more investigation and discover the invalid partion table is apparently on a WD MY BOOK 1tb

USB drive. I disconnected it and tried rebooting,,,it rebooted with no problems...so how do I fix the USB drive?

Enter BIOS and go to the "Boot Sequence" section. If the first or second device is something like “USB Device” or "USB Storage Device," then this might be what is causing the "Invalid Partition Table" message you are getting.


Change the boot sequence order so that “Hard Drive” is first, “CD/DVD” is second, and “USB Device” is third (or last, or disabled).

ok...I did some more research and found because the systemit was attempting to boot from had a  GPT protected partition the system did not like that when it was checking to see if it should boot from that drive. I the used diskpart and the clean command. I then created a single partition and formatted it. I used it no problems. But when i tried booting I had the same problem. I went into the BIOS under  UEFI boot sources and found a USB HD listed under USB/Floppy/CD (listed after ATAPI-CD-ROM in the boot seq)  Then under Hard Drive is listed my HD (SATA1)  My question is simple How do I  move the USB drive to after the HD?
