Fehlender Boot-Manager-Startfehler
Fehlender Boot-Manager-Startfehler
Hello, recently one of my HDDs stopped working, so I disconnected it to try data recovery. After that, every time I restart my PC, I encounter a missing Boot Manager error. It seems the OS should be installed on the SSD, but it’s not. The drive only held pictures and documents, no programs. I checked the BIOS settings for boot order, but it still won’t start. The only solution is to go into the boot menu and select the SSD. Is there a way to fix this without formatting? Thanks ahead.
I experienced a similar problem. I placed my HDD inside a USB external case. Started booting from the SSD, then connected the HDD. After that, cleared all remaining Windows files on the HDD. In my situation, there was an OS already installed on the HDD.
You can utilize a Windows installation drive and select "Repair Your Computer" or opt for alternatives such as EasyUEFI https://www.easyuefi.com/index-us.html
Verify the drive is the first one detected in BIOS. If yes, you must use an installation disc or thumb drive to start the process. After insertion and booting into install, select "Repair your computer." Next, choose troubleshoot and proceed to advanced settings. On advanced options, try automatic repair or startup repair if available.
uncertain about the setup, but it might relate to a single MBR and UEFI partition configuration. right now I see the DVD drive and MBR disk listed, but not the UEFI drive. during Windows 7 recovery I see both and then get a warning about the UEFI drive. while trying to rebuild the system I used a disk part to clean and switch everything to an MBR-based setup. just in case, people often face problems with dual booting UEFI systems.
This problem has persisted for some time. Without the bootmanager it's still possible to start the operating system. I managed a Windows 7 installation that worked this way—just needed the installer disc on the DVD. Other bootable drives also succeeded. You'd see the message asking for any key to boot from CD, but if you didn't press it, the system would boot from the OS itself. I eventually tried cleaning and reinstalling, though I'm unsure if this will apply to others or why it happened to me. I didn’t back up the drive before attempting a wipe, which I later regretted. (Note: I can still install other operating systems like Linux Mint, Manjaro, and Windows Vista without issues.)
