AN515-54-563Y Bios does not show boot options
Hi, i recently purachsed Acer Nitro AN515-54-563Y. It came with 1TB HDD and Windows 10. This laptop has two nvme ssd ports. I purchased crucial 1TB nvme m.2 ssd device and installed it. Windows detected the ssd drive and i initialised it, formatted it as GPT. So now disk0 is HDD which is running windows and disk1 is SSD which is blank.
Now i want to install Ubuntu on disk1 SSD. I prepared a ubuntu bootable usb following instructions from Ubuntu website. Now when i restarted my laptop, it booted from USB and got installation menu. But when i could not see the ssd drive when it asked me to select location for install. Not sure why it was only displaying disk0 that already has windows. I canceled installation and removed USB.
Then i went into Bios, i could see ssd on the information panel. But on boot menu i could only see Windows boot manager and did not see any other device to alter boot priority. I am not sure how it booted from usb at the first place. Anyways i disabled secure boot, disabled fast boot, set sata mode to AHCI, and save and restarted. Logged into Windows, now i could see ssd drive in disk management but ssd was disk0 and hdd was disk1. I reentered bios and could not find ssd on bios information panel. So i changed sata mode back to Rst premium with Optane. And ssd was visible in information panel.
Questions:
1. How can i view variuos devices connected to laptop in bios boot menu to set boot priority.
2. Is it possible to install multiple OS on different devices. I dont want to install on a different partition on the same drive.
3. If i clone hdd onto ssd using Cloning softwares that crucial recommends, and restart, what will happen or what should happen. I havent tried this option yet as i am afraid it might confuse Bios and system might not come up. Basically i want Bios to let me decude which device i want to use to boot.
4. Can i install Windows 7 on the new ssd.
Boot mode only gives me UEFI and no other option.
