Ubuntu 21.04 sees only 1 storage to install

I have 4 storage drives on my system.

My goal is to install 21.04 on the 1 TB empty drive listed as Disk 1. It's a regular HDD. The windows OS runs off a nvme currently and I do not want to touch that. Booting into Ubuntu and going in for an install, I for some reason can only see one drive to select - Disk 2 Ubuntu Installer

Drive detected by Ubuntu installer

Now, when I click the drop-down, none of the other drives are detected, not even Disk 1. Other disks are detected by Ubuntu in the Disks application though and this is what they show up as Disks detected in Ubuntu

Drives are detected in Disks but not the installer

Aside from a suggestion to remove other drives and install Ubuntu on its own, I'd rather have the convenience of Grub to load into whichever OS I'd like. BTW, drives are in AHCI in Bios with no secure boot or fast boot. I've tried to format the target drive in ext4 and without any format as well.

The same setup did work when installing Ubuntu 20.04 though. That version was bugged out and was frequently locking up the system and hence, thought of a fresh 21.04 instead. What have I missed out here?

Hello, is windows shut down properly, with fastboot disabled?

Yes. Ubuntu installer is loaded from a USB by selecting the boot from BIOS. Fastboot is disabled

Some also need UEFI firmware update & SSD firmware update. You can disconnect drives and then after install run `sudo update-grub` and grub will search for other installs & add then to grub menu. All systems must be in same boot mode, or all UEFI or all BIOS. Grub only boots working Windows, so you want to keep Windows boot loader in UEFI (or if BIOS in MBR), so you can always directly boot Windows. Windows is known to turn fast start up back on with some updates, so then grub will not boot it, until you turn it off again.

I will give that a try. Originally, when I attempted to dual boot with 20.04, I had an Intel RST issue. Post reverting to AHCI and making the necessary changes to Win 10, Ubuntu 20.04 installed but had a lot of lockups. 21.04 under the same setup, AHCI, No secure boot and no Fastboot only sees one drive in the installer. Thanks for the suggestion

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
