Hello, I have recently got a new case which came in with a 240gb gigabyte sata ssd that had windows in it. Booted fine for a few times, suddenly stopped being recognized as a bootable drive in BIOS. The thing is it is sometimes recognized and boots fine but %80 of the time it doesn't. I have CSM enabled on my board and the SSD is not partitioned as GPT as I saw in DISPKART. When I try to reinstall windows on it it shows up as unallocated space but I cannot for the life of me allocate/partition it for some reason. DISKPART gives me an I/O error when I use CREATE PRIMARY PARTITION. Is it the disk that is faulty? Or is it a wrongly partitioned disk or something I'm completely missing?
