I wanted to change the boot order to USB first on a Windows8 Samsung (NP300E5C) laptop to install LinuxMint, but there was only "1. Windows Boot Manager", no USB or CD option. So I started fiddling with the settings, and disabled Secureboot and changed the boot mode from "UEFI only" to "CSM only" to see if there was a change. Rebooted, and pressed F2 to enter Boot settings, but the laptop crashed and rebooted, crashed again after one second and reboots again, crashes, reboots seemingly infinitely.
Edit2&3: I disassembled the whole mainboard and exchanged the CMOS battery with a 10 Eurocent coin for two days. Now the BIOS settings are restored to default, and I can start again (but only with the HDD plugged, else I have that crash reboot loop). Now I'm at square one, because there is only 1 device in the boot order and it is "1. Windows Boot Manager". I want to make the laptop start booting with CD/DVD drive, then USB, then Windows. Any ideas?

have you tried removing tried removing your HDD and connecting it to a different computer to see if you can have access to your files? or Insert a different HDD in your HDD port to see if your computer reads it? – antzshrek – 2017-09-07T11:25:39.690
No need, because the problem is not the HDD, because the problem persists when I unplug it. – JML – 2017-09-09T09:03:04.163
