screwed bootloader
« on: 2021/03/05, 17:48:12 »
I installed siduction (5.10.20-towo.1-siduction-amd64 cinnamon) on ssd BEFORE installing windows 10 (on a 3rd partition) and lost my grub bootloader. Can someone please help me restore it so I can boot both operating systems?

Thanks unklarer,
but I have no idea how to enter those commands and Iā€™m afraid of screwing up the whole thing

^I'm sorry if you don't know how to enter the commands.
In any case, you would have to chroot into the siduction system to restore the bootloader.

My suggestion:
Install the Cinnamon with this  https://news.siduction.org/  new. I think it is the shortest way for you.   ;)

Remember, you can't install $M-Windows after LINUX if you don't know how to fix the Linux bootloader.   :)

This^!
If you don't have any personal data on the disk, start again and install Windows first, then install siduction. siduction install should detect Windows and automatically include it in GRUB.
If you do have data you could back it up to an external drive and restore it afterward.

Another option could be to boot into siduction from your system Boot Select menu and reinstall GRUB. Yet another option could be to boot siduction from a USB key with rEFInd and reinstall GRUB.

Thank you for replies.
I found that a program that I need to run in windows10 can be installed on linux now, so I zero wrote the ssd and (fresh) installed siduction kde.
Now I will no longer have any windows related dual-bootloader type computer problems!
