Hey,
I have a Dell inspiron 15R laptop with a haswell i7
I cannot boot from USB on this laptop, only sata (hdd/dvd)
I have bought some DVD-DL writables with 8.5GB capacity
I have downloaded Mojave Olarila raw image and High Sierra
I am confused as to how to mount the EFI partition of the raw image so I can update the EFI to suit this laptop with the available preconfigured OpenCore EFIs
I initially mounted High Sierra
hdiutil attach -imagekey diskimage-class=CRawDiskImage -nomount
Was how I got the image to disk5
then I tried some instructions on this website for mounting EFI
sudo newfs_msdos -v EFI -F 32 /dev/disk5
which gives an empty mount folder.
I gather I messed up a bit with this last command as its mounting the entire image as one fat32 partition
I don't know how to undo this. Any time I hdiutil the image it automatically sets to being just one EFI partition
I haven't mounted Mojave yet.
