I have a problem with the installation of any system Main target is Pure. I recorded the image from tails with GNOME disc and have boot message missing os , so tried other distr like ubuntu alpine etc and the same error missing os or isolinux.bin missing or corrupt… the only thing that works is tails.
Disc Os is Windows dualbot but are problems like 1234F and when It loads Windows just blue screen and error srttrail.txt . I typed in the terminal some advice to rebuild MBR and made another error “Reboot and Select Proper Boot Device” I have a usb with iso windows to perform a clean installation but when booting is a black screen not missing os. So whats wrong and what’s best solution cause now ripped data from disc so now target is install Pure OS but booting error is Missing OS .
