YaPaY Posted August 20, 2020 Share Posted August 20, 2020 (edited) Hello, a few days I started bootcamp to prepare windows 10 installation usb. My 500gb HDD had a small FAT partition (50 GB). Bootcamp merged it with system partiton. After first boot I saw BIOS screen, the PC could not boot from SSD and in BIOS I was seeing my HDD only Legacy version. now I can boot only USB and without USB there is no way to boot up. Maybe I can fix this with Openshell.efi but I do not know which command would help Apperently bootcamp corrupted the HDD s Master boot record. (EFI partition stays with files no problem here) I am using OC 0.6.0 and asking for help to boot again from HDD.
