Replace
path\to\recovery.img
with the actual path of the recovery image
fastboot boot path\to\recovery.img
If it asks you to run it once again, do so
adb shell msc
diskpart
Use
list volume
to find it, replace "$" with the actual number of WINNABU
select volume $
assign letter x
exit
Note
This process will take +- 20 minutes. Do not worry, this is normal.
- Unpack the driver archive, then open the
OfflineUpdater.cmd
file (if an error shows up, runOfflineUpdaterFix.cmd
instead)
If it asks you to enter a letter, enter the drive letter of WINNABU (which should be X), then press enter
Make sure to also change the UEFI image in Android, otherwise you may face a "blue screen of death" (BSoD) when booting Windows later.
adb reboot
