I have a 750 GB HDD with two partitions. One partition has 550 GB with my files so I want to save it. The other partition had Windows 7 on it.
So I booted Windows 10 from USB, formatted the Windows 7 partition but I was unable to install Windows 10 because it requires GPT partition table. The current table format is MBR.
So now I am unable to install Windows 10, also I am unable to install Windows 7 because in will not boot, giving some disk error.
I booted again from Windows 10, deleted the formatted Windows 7 partition, tried to create it again, but the space remains unallocated.
I don't want to loose my files so I can't reformat the entire hard drive as GPT. DISKPART will only list the entire HDD so I can't work with it.
Any suggestions please, to save my data and install Windows 10?
