I have a dual-boot system with CachyOS and Windows 11. Currently, Windows is the default OS in my BIOS settings. When I want to update CachyOS and need to restart, I usually have to quickly hit the F11 key to access the boot menu. I'm wondering if there's a way to reboot directly from Linux to Windows or vice versa without changing the default boot option each time. Is there a command or script, like a .bat file, that could help me restart directly to CachyOS from Windows?

Many boot managers can remember the last OS you booted into, helping you switch easily if you make a selection before the timeout expires. This could streamline your switching process significantly.
If you don't need full hardware access for both operating systems, consider using a type 2 hypervisor. For instance, I run Linux and Windows VMs using VMware Workstation on Windows. This way, you can quickly access both OSes without constantly rebooting, plus you get features like snapshots and easy backups.
If you're using GRUB as your bootloader, you can enable OS-Probing to detect your Windows installation. This will allow GRUB to remember your last chosen OS, and you can set GRUB as the default bootloader. You might also want to adjust the timeout settings so that you can select an OS without needing to rush.
You could use a command like `sudo efibootmgr --bootnext XXXX` on UEFI systems, where 'XXXX' is the boot option for Linux you want to select for just the next boot. This makes switching a lot faster without needing to go into the BIOS each time.
Just make sure your Linux bootloader can manage both OSes efficiently. Set a boot timeout where you can just select the OS with your keyboard. You could do what you've mentioned with a script, but it might be an extra step you can avoid.
Thanks, I'll definitely explore that option!
I really want both OSes to access my hardware fully because I game a lot. But having a backup plan with Windows would be handy just in case something doesn't work on Linux.
