As much as I wanted to support Linux hardware vendors, economics (I'm retired.) led me to purchase this Lenovo ThinkBook 15 Gen 3 (AMD Ryzen 5 5500U) with 20GB RAM and a 500GB SSD drive.
After much thought and some trials I decided to go with Obarun as my main boot on this laptop. It was no light decision since I boot 30 different Linux distros (I have installed over 100 distros since 2000.) on my main 3 DR Intel i5 tower. I left 250GB to Windows and divided the other 250GB to 2 ext4 partitions: 70GB for "/" and 167.3GB to "/home"
I did not follow the Obarun pre-installation instructions of creating another esp partition. I wanted to use the drive's own SYSTEM_DRV vfat esp partition despite the fact that it was only 260MB. Even after copying over the 2 files from /boot I still had used only used 29% (74MB) of the partition.
- First I used a lsblk script to determine that the esp partition was nvme0n1p2 - It was the only vfat partition and it was labeled SYSTEM_DRV.
- Then I mounted that partition to /mnt/esp
- cp /boot/vmlinuz-linux /mnt/esp/
- cp /boot/initramfs-linux.img /mnt/esp
- sudo efibootmgr -c -d /dev/nvme0n1 -p 2 -L "Obarun" -l \vmlinuz-linux -u "root=LABEL=Obarun ro initrd=\initramfs-linux.img"
That was it. Thereafter the computer booted to Obarun.
The key points are the "-p 2" since the esp partition is on the 2nd partition NOT the 1rst and I labeled my "/" "Obarun" via e2label.
To boot Windows 11 Pro requires pressing F12 quickly as the computer is turned on or reboots.
