‪startup repair didn't fix it, i guess it was too cursed. i'm instead installing windows 8.1 with some product key i found online (my burned windows 10 dvd has rotted but my windows 8.1 one is still good), since i know that'll create a usable gpt windows bootloader setup‬

‪disk partitioning and bootloaders are so goddamn arcane‬

‪installing windows 8.1 is so nostalgic, i miss when microsoft weren't evil‬

hello from the last good version of windows. i missed this so goddamn much. windows 8.1 was a strange creature but it had the prettiest desktop theme and windows 10 just threw it away ;_;

(only installed it to unfuck the boot setup, won't be actually using it except for funsies)

and hello again from windows 10! i did need to do a little manual fixing up from the windows 8.1 side; with its bootlader installed, i could go into the windows 8.1 recovery command prompt and do bootrec /rebuildbcd to make it find and add windows 10 to the boot list ^^

as a "computers person" i do not know how to solve the problem correctly the first time, what i do have is an endless list of strange tactical maneuvers that might solve a problem and an ability to prioritise them
