tchitou Posted August 7, 2015 Share Posted August 7, 2015 Hey guys, I happen to have an installed Clover EFI on the wrong disk (the partition is on the 2Tb drive I only use to make backups). I wanted to clone that EFI partition to my system SSD EFI partition but as soon as I do that (or install clover on it), I can't boot my computer at all and can't even access the bios. Black screen.... Then the only way is to disconnect the SSD drive and boot on Windows. As soon as I format the EFI partition on the SSD, my system boots normaly.... but it's using that slow EFI partition of the not-so-safe backup disk.... Would you know what causes that? Thanks a lot!!! Link to comment https://www.insanelymac.com/forum/topic/307469-clover-installed-on-the-wrong-efi-partition/ Share on other sites More sharing options...
falanx Posted August 7, 2015 Share Posted August 7, 2015 It's weird you can't even access bios. It's acting like when my hard drive failed. First then I would try to add Clover as UEFI boot option in bios pointing to the SSD and not the hard drive. I would still boot from the hard drive and boot from it and move EFI to the SSD. Then at restart I would open that menu where you can choose which boot option to boot and try to boot from the SSD.

JahStories Posted August 7, 2015 Share Posted August 7, 2015 maybe the partition table of the drive is damaged, it seems like the system gets stuck checking the drives, that would need a plain format, but i'm just guessing... But why cloning the efi partition from an "empty drive" to a drive where there is an OS installed (and probably other data on the efi partition) and not doing a regular clover installation on the correct drive? And btw you can keep clover installed on any drive you want, it's just makes you boot it's not mandatory to install it on the drive where there is OS X P.s. Please edit your signature with the specifications of your machine so it will be easier for us to help.

If I chose the boot option pointing to the SSD then I wouldn't have to press Boot options at restart. Maybe the system doesn't like 2 clover EFI partitions? maybe the partition table of the drive is damaged, it seems like the system gets stuck checking the drives, that would need a plain format, but i'm just guessing...

I had installed Paragon HFS+ on windows and it completely messed with my HFS partitions (my OSX system and its clone), so I had B-tree catalog errors and was unable to boot both systems... A nightmare! I did a clean install and used the Yosemite Assistant to migrate the data from the clone to the new installation. I tried the regular clover installation on the correct drive first, of course. But it didn't work, so I figured, let's clone the working EFI partition... Didn't work either... I know Clover can be on any drive, but right now it's on a slow (not SSD) backup drive I don't really trust. I'm a bit scared that the day the drive dies I'll have tons of troubles to make my system work again. Next step will be what falanx advised and starting the system with the backup drive plugged out. If that doesn't work, I'll clone my OS to an external hard drive, unplug every drive except for the system, clean install again, migrate from the external drive and hope this solves the issue... It's just very time consuming Link to comment https://www.insanelymac.com/forum/topic/307469-clover-installed-on-the-wrong-efi-partition/#findComment-2158597 Share on other sites More sharing options...

tchitou Posted August 7, 2015 Author Share Posted August 7, 2015 Yay Paragon!! At least I know what no to do next time. I hope Macdrive still works like a charm.

falanx Posted August 7, 2015 Share Posted August 7, 2015 Yeah, you can directly set SSD as the first boot option, just I am used to laptops and everything is built in and time consuming to move and take out, so as of precaution I thought it is better not to chose it as first boot option because of your computer didn't want to boot even to bios with SSD. I have bad experience with Paragon too. Had to format my whole drive and reinstall everything because it corrupted everything. So now I use exFat for my external drive and for one partition in my hard drive to move files between OS X and Windows. Just I found it's better to format to exFat in Windows and not in OS X. When I formatted in OS X, sometimes I had to run fsck to repair it. 5 sec solution but exFat formatted in Windows seems pretty solid for me for both OS X and Windows can use it. And what I like the best that it is natively supported. Paragon and other solutions for compatibility gave me a lot of kernel panics and once a fully corrupted drive. I chose not to use them anymore.
