I formated only the C partition because I have data on my others and when I tried to install the new copy of Windows I got the following error: Windows cannot be installed to this disk. The selected disk is of the GPT partition style.
While I was looking for a fix I got a power failure and now I cant even boot my old Windows so I cant backup data from my other partition.
What can I do?
TLDR:
Erased C partition.Have data on other partition.
Laptop got shut down.
Cant boot old windows.
Cant install new copy of windows because: The selected disk is of the GPT partition style.
