Can't re-partion without wrecking Chrome OS #48

Closed Agent-Cain closed 7 years ago

Agent-Cain commented 7 years ago

I wanted to re-partition the new partition to have space to install an other distro on the ssd. What ever I try to do, I end up with chrome os out of order. Is it my fault or just not possible ? My plan was having 3 other debian based distros beside chrome os ...

reynhout commented 7 years ago

That's correct. ChromeOS partitions require special handling. Chrx uses the ChromeOS partitioning tool (cgpt) for this reason. As far as I know, no other partitioner will work.

Ok, then I will try it again with cgpt. But what I was doing was repartitioning the Ubuntu Partition, so I don't get where the problem is ..

reynhout commented 7 years ago

Any partitioning tool will have to rewrite the partition map for the whole disk, which breaks ChromeOS if not done properly.

Do you have a cgpt guid or something like that ? Maybe it's too late, but i can"t get it working ... ... now i can resize the ubuntu partition and chrome os works, but now ubuntu fails. I'd be happy for help

Do you have a cgpt guid or something like that ?

Do you mean "GUID", or "guide"?

If the latter, try running cgpt or cgpt --help. There's some way to coax basic usage info out of the binary, which is what I used. There might be more formal docs somewhere, but I didn't look.

If the former, I don't know the GUID of ChromeOS partitions, but you should be able to extract it from a working ChromeOS map.

I was looking for a guide, sorry.

Agent-Cain commented 7 years ago

okay, now I was able to make a new partition without crashing chrome os, and reinstall ubuntu with your script. Now there is a big space unallocated and when I try to install a new distro, every distro tries to set up new partitions ... which won't work obviously. Do you have any tips to go further ?

reynhout commented 7 years ago

I don't know what distros you're trying to install, but there should be an option to install to an existing partition. I know the Ubuntu installer (Ubiquity) is obvious about it, maybe others are less clear?

Agent-Cain commented 7 years ago

Right now I'm trying to install elementaryos besides ubuntu

Agent-Cain commented 7 years ago

Maybe I made the repartition job wrong. The new partitions file system is always unknown, not ext4. Additionally elementary os creates a linux swap partition, which I also couldn't set up with cgpt.

Agent-Cain commented 7 years ago

Okay, now I'm a step nearer to my goal: mkfs & mkswap both work without messing up chromeos. I was able to make 2 partitions and could install elementary os on one of them, on the other should be ubuntu but i can't see it or choose it ... ctrl + d brings me to normal working chromeos ctrl + l brings me into elemantary os

if I could swap now between ubuntu and elementary os, everything would work like I'd like to !

Wow a long journey ends :D Everything is no working fine. Thanks again for your tip with cgpt
