I did not sleep finally,i try to instal last sonoma when I format the disk in AFPS in the recovery, the process does not finish at 100% but opencore restarts, I reopen recovery utility of disk and it is formatted in HFS logged, and I install all the same but with 15mn remaining the installation does not restart on osx, but on windows and I checked the disk is always empty after this restarting of windows. I turn in loop, the bootlooder always remains logo window + logo olarila + nvram screen.zip

i try with original MOD it work fine !!! i don(t know what happened. Thank you for your help

?

I found the solution to reset the nvram without a bootable key. your last EFI made a few extra lines :. Archive.zip

thank you, I'm so bad luck, it's been 5 hours that I haven't been able to boot any EFI key in my bios I don't know why so I can't even test your EFI there's no nvram in the bios? because it always displays opencore in boot devices even when there are no bootable keys on the computer.

thank you for your reactivity, I've tested your EFI in every way but i still get the same startup screen : - however I had well deleted the EFI partition and replaced by the ice lake portable MOD before your EFI - there is no CSM in my bios, I have deactivated FAST BOOT too - I have well deactivated the secure boot - I have also deactivated the intel VT-D - well made copy/paste EFI folder by replace without merge - I have even used usb3 keys in the usb2 . port; - I've also used my usb3 key in a usb3 hub on the usb2 port Maybe I should stay on the startup and leave it on for 1 hour? because 16 GB doesn't decompress in 1 minute, does it? Can i ask u to make DSDT for this laptop please ? I send you info laptop on zip Lenovo ThinkBook 15-IIL 20SM.zip

Hello, I really need your help, for the last 5 sleepless nights and days I've spent hours installing ventura or sonoma on my Lenovo 20SM 15-IIL ice lake i7 but impossible despite all your tutorials here and even on youtube to just start the minimal, I don't understand. I'm not a specialist, my knowledge is limited and I can't get any further. Burn out! Can you please help me? I enclose a screenshot of my bios and the black startup screen screenshot.zip
