Hi there, hate to have my first post creating a help topic but here goes nothing. Please approach with caution, massive noob (hackintosh-wise).
So I followed the guide for High Sierra, created my bootable installation USB drive for HS, and everything works fine up until I have to format my drive (in this case a Samsung 850 Evo mSATA) to Macos -whatever- Journaled. When I press erase it gives me the error in the title. "Couldn't modify partition map" and it fails.
I searched the forum and the interwebs quite a bit, but none of the problems seems like the one I have here. I tried to preformat my drives as empty and "unallocated" using a win10 installation usb, my drives seemes "unmounted", so I went back and via the win10 installation usb I formatted them. Now they seem NTFS in the HS Drive Utility, and they are mounted, but now I have this error popping up when I try to format them (by them I mean only the SSD, I don't even know if the HDD will be visible in MACos in this state) according to the guide.
System:
AsRock H110TM-ITX
i3 6100T
8 GB DDR4 Ram
120 GB Samsung 850 Evo mSATA SSD
750GB WD Scorpio Black HDD
Intel 7265 AC Wireless card
Any advice? I attached a picture of how things look.
If the advice needs to be complicated in any way, please give an explanation too. As I said, I am a complete and utter noob to this kind of thing.
Thanks in advance
Edit: I tried to format my HDD to HS format, and it worked just fine. I get this error only on my SSD. Is it a problem it being an mSATA drive? I've done everything in UEFI bios as the guide said. Anything else maybe?
