Hey, so went to this link, and downloaded the Graphical 64-bit Intel/AMD iso and put it on my Ventoy formatted usb dongle and started on it, and chose Gnome LTS Installer.
Except that it cannot boot with below:
I’m wondering if this would ring a bell to someone, somebody who has already bumped into this before? 
modprobe: ERROR: could not insert 'hv_balloon': No such device
modprobe: ERROR: could not insert 'hv_netvsc': No such device
modprobe: ERROR: could not insert 'hv_storvsc': No such device
modprobe: ERROR: could not insert 'hv_utils': No such device
modprobe: ERROR: could not insert 'hv_vmbus': No such device
From my cheap understand, these are hyper-V guest drivers failing to load, so harmless if not running inside a Hyper-V VM and can be safely ignored.
I/O error, dev loop0, sector XXXXXXX op 0x0:(READ) flags 0x800
SQUASHFS error: Failed to read block ...
SQUASHFS error: Unable to read fragment cache entry ...
SQUASHFS error: Unable to read page, block ...
Looks like the root cause, the NixOS squashfs image cannot be read 
, so maybe, Bad USB drive, corrupted ISO?
Not sure what I can do about it
