I am trying to dual boot windows and ubuntu on a razer blade 15 advanced (2021). I had a lot of issues with 20.04 (mainly nvidia drivers not working) and after days of troubleshooting I have decided to switch to 21.10. I have confirmed that 21.10 fixes all the driver issues I was having, however, I have noticed something strange.

If I create a boot disk with 20.04 it can see my secondary drive with windows, however, the 21.10 installer does not detect this drive at all. I have looked through many posts and tried turning on and off secure boot, I see lots of posts about RAID but I don't have that bios option and it seems like a dell issue.

Furthermore, it seems that grub does not work properly. It launches into grub minimal terminal and I have to exit to get out of it.

Edit: After some additional investigation I have found that both 21.04 and 20.04 can detect the other ssd (with lsblk or fdisk) but not 21.10. I found another post that describes this issue, however, they only say that they downgraded the kernel or used the previous versions of ubuntu which I was having trouble with.

I've had exactly the same issue with a new Razer Blade 15 Advanced (mid-2021). While attempting to create a Windows/Ubuntu dual boot setup ... LTS (20.04) Ubuntu-based distros all are able to see the internal nvme drive but suffer from a lack of driver support (wifi and the nvidia drivers, for example). Meanwhile, the most recent 21.10 distributions run great with the live cd and are able to detect the wifi hardware, but fail to see the internal nvme drive and therefore cannot be installed.

I eventually was able to get a satisfactory setup running on my Razer Blade 15 by installing the 20.04 LTS release (in my case I installed Kubuntu with wired internet connection). After finishing the install I upgraded directly from 20.04 to 21.04 "Hirsuit Hippo" and installed all the available updates.

WARNING: Do not upgrade any further than this... I did try upgrading again to 21.10, but the system was not able to see its own installation drive and could not boot. That being said, 21.04 with the nvidia-470 drivers seems to work really well.

fwiw I've also filed a bug report here
