ok i have an archive of an os, where at that time it was installed on a second hard disk. i have changed some things around in my case and now there's only the one hard disk. when i try to boot the os i've mentioned, it won't boot because i imagine the boot information is wrong. i have a file explorer program that can see and allow changes in the hidden isr folders - i figure if i delete the boot folder from that snapshot and replace it with another boot folder from a snapshot that was installed since i changed to only one hard disk, it will work again. the trouble is i cant delete the boot folder in that isr folder, i get an error "access is denied" does anyone know how i might approach taking full ownership of the folder so i can do this? thanks!
