I've searched for people with similar problems but none of the fixes seem to be working for me.
I have a Windows 7 (200gb + 100mb reserved partitions) and the rest (~800gb) as unallocated. This is how it's represented in Windows and miniPartitionWizard/EasyBCD, both of which I have used (as advised elsewhere) to edit/repair the partitions and attempt to repair the MBR.
When I boot from the 13.1 live-usb and view the disk with gparted I get this prompt:
/dev/sda contains GPT signatures, indicating that it has a GPT table. However it does not have a valid fake msdos partition table, as it should. Perhaps it was corrupted -- possibly by a program that doesn't understand GPT partiotn tables. Or perhaps you deleted the GPT table, and are now using an msdos partition table. Is this a GPT partition table?
n have the same results of showing the disk as completely unallocated, though.
If I say no, I get the additional error
No partition table found on device /dev/sda
If I try and create a new partition, which is expected.
sudo parted -l throws the same error. I've tried reinstalling Windows several times, even if I don't change the partitions at all the Windows installation doesn't show in
gparted. Am I missing something here?
