Cannot install on Tecra A40-G-123

[Samuel Altunian]

Hi all, I try the installation on Tecra A40-G-123 -
CPU: Intel i5-10210U
GPU: Intel® UHD Graphics 620
It processes the installation and then after rebooting from the HDD it freezes and goes either to a boot loop or back to the setup.
I tried Ventura, Sonoma and Sequoia with the same result.
I used the "plain" EFI for the Comet Lake as this is the processor.
Any advise where to dig further?

Thanks for any help!!!!!

No, it is build in, on the mainboard. But it is an ssd.

Use Mobile CometLake efi and add -igfxvesa for easy installation

[Samuel Altunian]

Thanks for the advise, but I used this right EFI in the past too, and it happends the same - the "initial" setup works until the firts reboot where the laptop boots from the internal drive, then after a unix lines screen comes up the Apple logo and a progress bar shows up. When 10% of the bar ere filled, the laptop reboots.

Do you have other ideas?

Thanks @MaLd0n but as already stated, this is the exact EFI folder that I used and added only the -Igfxvesa argument. Ant this did not change the outcome.

what else can you advise?

Post one video or photo on screen error

[Samuel Altunian]

There is no error, it just reboots at a point and keeps rebooting

Do you need a screenshot of the last few lines from the log befor the auto reboot for example?

Or a vide of the whole boot

Video on boot

Hi @MaLd0n here is the boot video - 

 

During the boot it just hangs and reboots...

And as already said, I created installer USBs of OSX13,14 and 15 with the right EFI and the result is the same.

What can be done next?
