windows 7 install not working

[dreamcast2000]

i recently took a 500 gb ssd from my old windows 8.1 school laptop and put it in my computer. i have already cleaned it and converted it to mbr. i used an iso that had image updater applied to it. when i get to the "where do you want to install windows?" screen and select my ssd, it gives me the error "windows couldn't install to the location you chose. please check your media drive." alongside the error code "0x80300024". how do i get past this? csm is enabled btw
