 catmater what SSD are you using in your setup?

SK hynix SC311 SATA 256GB  (70000P10) m2 revision - 450/460 mb/s  read/write perfomance.

I'm drop out SATA-100-series-unsupported.kext , i think is useless for my hardware, but maybe it wrong?

I decrypted and removed bit locker, but I still have the error of disk IO failed, I am going to go back to try with my old clover configuration.

 

EDIT:  Nope, nothing works anymore.

Try to this config - added some missed driver for mojave to clover.

Try my Mojave guide here

Use this bootpack, files goes into /EFI/Clover replacing the default installed by Clover

Kexts in ../kext/Other/CopyToLE should be copied to /Library/Extensions after installation as part of post install.

Good luck

Thank you so much, have been fighting audio issues for days and your bootlick works!!!

Make sure you set BIOS as this

Set to Default, apply, then set SATA Operations to AHCI, set Boot List Option to UEFI, Disable Secure boot

I did that and it didn't work. how can i fix this ? like it says disk2s1 error, and i only have 2 disks the internal and the us drive: is it the internal it is having a problem with ? or the usbdrive ?

 

EDIT  : Could the windows OEM REcovery Partition be the problem ?

Any one ? I truly can't boot to the installer.

Disable the drive and see if you could boot up the USB installer.

I had the issue on PM981 and needs to be replace with a supported drive, but unsure of PM961.

I disabled the drive and the problem persisted, I assume it's my USB installer. Very weird because I already did boot the installer before on the same laptop like hours before this error came up.

 

I'll create a new Installer.
