That switch is done in the BIOS.

I bought my PC years ago with only a HDD. I added a SSD myself afterwards. When I booted my PC after a hard shutdown/electricity fallout I had only my HDD in BIOS. I then boot from HDD, get an error and let the PC reboot. After a few times the SSD would be recognized in BIOS and I could change the SSD to default.
I got tired of this proccess a few days ago and found a tip to disable the hdd-partition with diskpart. The first time I had a hardreset again (mouse and keyboard froze and pc didn't shutdown with a single press on startbutton), I couldn't do the HDD boot-trick and tried changing the cables from hdd to ssd (ssd in sata1). This didn't help. In diskpart I made the SSD partition active. I now can see the SSD in BIOS, but booting gives an error "An operating system wasn't found.". When I retry diskpart, the partition could be made active again. It seems like this resets..
Bootrec.exe /FixMbr was successful
Bootrec.exe /FixBoot gives no access error (there could be some parts left of a dual boot setup)
chkdsk gives no problems found
Mediatool boot:
- This PC can't be recovered with start-uprepair.
- You need to choose which installation of Windows you would like to put back when using Systemrecovery.
- Reboot, select a operating system and select Systemrecovery. No systemcopy available.
How could I make my pc boot again?
PC: MEDION AKOYA P5367 D EU (MSN: 10015458)
Motherboard: MS-7728

2018-08-22T15:10:30+00:00 Hi,
Part of the problem may be with how your Installation Media was created...
Like I mentioned before, but the opposite... Or that you need to boot with it differently... That would explain the Bootrec.exe /FixBoot gives no access error
What you might look for is "UEFI" boot device in the BOOT OPTIONS menu on the manufacturer's screen where you enter Bios... Just a different key...
Something like ESC, F9, F11, F12...
You might see something like "UEFI Optical Drive", or "UEFI USB", as opposed to simply "Optical Drive" for instance...
A Flash Drive for UEFI Bios should be "Initialized" as GPT (GUID) and have a file system of FAT32...
A Flash Drive created for Legacy Bios using a MBR Initilized drive, formatted as NTFS MIGHT work if you select it as a "UEFI" drive in Boot Options...
GPT drives as required for a boot device in UEFI machines do not use "Active""Not Active"... It is not a valid setting for a GPT drive..
BTW... UEFI machines use "WindowsBootManager" as the Boot Device, not the actual drive\partition it is on... (EFI Partition)...

- BIOS is UEFI
- SSD is (now) visible in BIOS op both places
- If I am right, I can only run Diskpart and Boot Repair from the bootable installation media, because the OS isn't booting. I can't get it in safe mode either.
