Another dual boot story / Limine

Issues & Assistance
1

Hi,

New comer to cachy os I probably did a beginner mistake.

I install fresh computer and wanted to have dual boot with win11.

Both are installed in 2 nvme ssd and I installed cachyOS first. I know I should have done the oppsite but was too excited to test my new computer with cachyOS! Wion11 is there just a spare wheel for very limited softwares.

I let cachyOS all default choice so now it is using Limine as boot loader which is new to me after decade of GRUB :wink:

Long story short I do not see win11 boot option in Limine. Sounds like a common issue so checked the wiki page

And there surpise starts when looking at the partition table

lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT
NAME FSTYPE SIZE MOUNTPOINT
zram0 swap 62,7G [SWAP]
nvme1n1 465,8G
├─nvme1n1p1 ext4 16M
├─nvme1n1p2 ntfs 465G
└─nvme1n1p3 ntfs 787M
nvme0n1 1,8T
├─nvme0n1p1 vfat 4G /boot
└─nvme0n1p2 btrfs 1,8T /var/tmp

As you could guess nvme1n1 is my windows disk and nvme0n1 is my linux disk.

I was expecting to find a vfat parttion on my windows disk but to my surprise I found a ext4 one!

I am confused … any idea?

I think you need to run: limine-scan, for windows to be added as a boot entry.

worked thanks! For some reason after first boot I did not find the command. Still does not explain the ext4 parttion and no vfat one on win disk :confused:

Because you installed windows second it detects the ESP of the linux install and uses that. This will cause you problems in the future by the way. Windows has the tendency to take over the ESP during big feature updates. That is why you should install windows first and then linux. Linux allows you more control where to create the ESP.

Then i will start over :rofl:
