Kann nur noch in Linux booten?
Ich habe mir vor 2 Tagen Mint installiert, ich benutze zum ersten mal Linux. Ich habe es auf einer zweiten SSD neben Windows auf der installiert, nach dem ersten mal neustarten bin ich in Windows gelandet und musste die boot priorität umstellen, danach hat alles geklappt und ich habe auch schon einiges über linux gelernt. Gestern wollte ich wieder auf Windows booten und stellte fest, dass es diese boot-option nicht mehr gibt und nur noch linux erkannt wird. Ich habe in Linux dann eine boot-stick mit der Windows-Iso erstellt, dieser wurde auch nicht erkannt. Ich habe dann auf meinem Laptop mit der Installationssoftware vom Microsoft einen boot-stick erstellt, dieser wurde erkannt, kann allerdings mein Windows nicht reparieren. Die Windows-SSD habe ich nie modifiziert, an was kann dies also liegen und was sollte ich tun?

Hello BlackRiver22,
Unfortunately, such problems are always difficult to solve by “early diagnosis”. I hope my answer will help you a little bit. You should disable the CSM mode. It not only deactivates Secureboot but all UEFI functions. Modern Linux systems are available with UEFI and often also the UEFI function extension Secureboot. On a pure Linux system, I would always deactivate Secureboot as there may be problems with subsequently installed drivers. In addition, there are still distributions that do not work with Secureboot e.g. Nobara Linux. UEFI itself is needed for many functions (e.g. PCI-E Re-Bar) and therefore your firmware should also run in UEFI mode. Secureboot can be activated and deactivated independently of UEFI mode provided your firmware offers a suitable option.
As soon as Windows comes into play as an operating system, UEFI is absolutely required and with Windows 11 also Secureboot and TPM2. Dual-boot systems have unfortunately become quite complicated in recent years. Again and again the Windows comes overwrite the GRUB Loader during an update so that only Windows can be booted. A few months ago, a faulty Windows update put multiboot systems completely lame around the world.
As for your problem, I advise you to reinstall your system. What it looks like is your situation:
SSD 1= Windows with GRUB Loader
SSD 2 = Linux Mint
Ideally, it would be to completely separate the two systems, so to use Windows with the Windows boot loader and Linux Mint with the GRUB boot loader.
SSD 1= Windows + Windowsloader
SSD 2 = Linux Mint + Grub Loader
Activate Secureboot and TPM2.
First install Windows on one of the two SSD’s. After installing Windows, deactivate the Windows Fastboot function as this can cause problems when booting other operating systems. Then install Linux Mint on the second SSD and keep the GRUB boot loader not installed on the Windows SSD but on the same SSD on which Linux Mint is installed. You can then select which system should be booted at the start of your computer via the UEFI Bootmenu. Some motherboards provide a function that ensures that the UEFI Bootmenu is displayed at each start. Everything else will cause you more or less trouble sooner or later.
Probably a Windows update shot the Grubbootloader.
There are two options for a dual-boot installation – install Windows on Linux a virtual machine or install Linux into a virtual machine on Windows.
A computer with Windows and a second computer with Linux.
You can always transfer the old data from the old record to the new record.

I think a boat is too dangerous:
I would have installed Linux on a new SSD. You can never know if there’s a problem. Well, it’s more complicated to change the SSD every time, but is the safe option.
In your case, I would go to a PC-doctor so that he fixes it or reinstalls it.
I have installed it on a second SSD and dual-boot should normally work smoothly. And I want to help myself with this problem
You must configure your dug, systemd-boot or whatever, correctly for dual boot.
Did I try my Windows but just won’t be recognized as an option to boot, neither in the boot menu nor when I added it in grub
What does your partitioning look like?

To the SSDs with the operating systems I added them, the other 3 are 2 HDDs and the Windows bootstick
