Note this may be the wrong sub I'm in but I don't know where else to ask.
I wanted to install windows from a USB I made and I deleted the data in the C Disk but now it's telling me that the disk is GPT and the problem is that I created an MBR flash as it seems. I have data in the D disk that I really don't want to lose and without access to another laptop, I'm afraid I can't necessarily create another OS. Although I can get another USB flash and make something like a Ubuntu USB if it's necessary. Is there any way for me to get around this, install the OS and get to the data without having to lose it?
