Before anything, I would like to apogolize for my bad English, I’m like so many french guy bad at other languages !
I got a problem with my Thinkcentre 7635-W1n. It’s a computer I bought with W10 OEM pre-installed on a HDD. However, I wanted to replace this HDD by a SSD. So when I receive the computer I make the replacement and I erase the HDD for using as a save HDD.
After create an USB boot with Rufus, the screen displays « Error 1962, no operating system found ». After many tries :
But this recent tries don’t lead to boot on USB. Now, after try booting on USB, I have a white dash sign in the top left corner.
I read that there is a problem with the Lenovo with an OEM OS but can’t find the solution myself.
Thank you for reading my post and have a nice day

I'm sorry making a double post, but I can't find the edit options.
To complete my first post after viewing the trade : "Help us to Help you" :
- the system information : Lenovo 7635-W1N with Windows 10 OEM (64-bits I think)
- for the updating of the BIOS : BIOS version - 5CKT61AUS.
The BIOS version 5CKT77A seems to be the latest version, I dl it but when I read the readme.txt, I was a bit lost with the information and I don't know if a BIOS update can solve my problem.

Considering the age of the system, you may be more successful burning a DVD (CD for BIOS) with the ISO image and updating via the optical drive (USB drive is more apropos for newer systems.)

I succesfully updated the BIOS ! But with an USB Key I have the same problem for booting Windows. So I create a DVD with W10 and I have no success, the screen displays and locks on "Booting an AHCI DVD-ROM". So I change a setting in the BIOS : I turn "Legacy Free" in Enabled and when I try to boot from the DVD-ROM the Windows logo appears
However, I have a question before installing Windows 10. The SSD is in GPT format and I don't know if I need to convert the SSD in MBR format, because when I boot on DVD there is no "UEFI" before the DVD ROM on the boot menu and I don't the if the BIOS is UEFI ou MBR.
So there is a photo of the Legacy Free explanation.
