Hello I'm trying to install Qubes 3.1 but after booting in UEFI mode I
select `install Qubes` and the installer rapidly enters dracut emergency
shell.

here are the last lines of `cat /run/initramfs/rdsosreport.txt` :

dracut: Scanning for all btrfs devices (repeat 10times)
dracut Warning: Could not boot.
dracut Warning: /dev/root does not exist

Any idea on how to fix this ?

Can you send full /run/initramfs/rdsosreport.txt? You can for example
copy it to some USB stick (other than installation media).

I can't see anything even close to Qubes installation media label. But
there are USB2.0 and USB3.0 devices detected, so probably not a driver
problem. Are you sure that you've written the installation image
correctly?

Well you're right I extracted the .iso onto a FAT32 formated USB drive
because I thought it would be better for the UEFI boot. I remade a USB
installer using dd and now I have a new symptom :

If I select "Verify source and install Qubes" the process freezes after
the test passes.
If I select "Install Qubes" I got this :

Ignoring BGRT : invalid status 0 (expected 1)
mce : unable to init device /dev/mcelog (rc:-16)
/etc/vconsole.cong line 1: 1=: command not found
/etc/vconsole.cong line 1: 1=: command not found
sd 4:0:0:0:[sdb] no caching mode page found
sd 4:0:0:0:[sdb] assuming drive cache : write through
mount: /dev/sdb is write protected, mounting read-only

And then the booting process freezes completely and I can only reboot
with ctrl+alt+del. I have to add that the Qubes graphical logo blinks
very briefly before it comes back to the command line and freezes.

Any idea on what is happening ? Is there a way to activate a verbose
mode so there is more detail on the failure reason ?

Since ctrl+alt+del does work, it isn't completely hanging. Most likely
some graphics driver issue. Are you able to switch to different console
(ctrl+alt+f2)?

As for verbose mode, its hard to enable in UEFI mode[1], you need to edit
xen.cfg file inside images/efiboot.img. I think the easiest way would be
mounting a second partition of the USB drive (yes, installation image
contains two partitions). Then find EFI/BOOT/xen.cfg and remove "quiet"
option.

It is true that ctrl+alt+del works and reboots 2sec after I hit that but
I can't change console with ctrl+alt+f2 or other.

I removed the quiet option but unfortunately it didn't help much since
the boot stops at random moments :

1st time : [OK] Started Load/Save Random Seed.
2nd time : [OK] Started Apply Kernel
3rd time : [OK] tarted Configure read-only root support
4 : [OK] Reached target Local file systems (pre)

It always stops after the logo blinks for less than a second. My
computer config is : http://pcpartpicker.com/p/3Z6pCJ
I have an Inno3D iChill GeForce GTX 980 Ti X3 Air Boss Ultra 6GB is it
compatible with Qubes ? Do you know if it's possible to buy a cheap
compatible card that I would stick into a second PCI slot and that would
get Qubes to work ?

I was able to fix the problem by adding "nomodeset" to xen.cfg. Now the
graphical installer runs normally but a new problem appears when I reach
the partitionning menu.

I make a partition for /, a partition for /boot and the EFI partition
is already existing from windows. Problem is that when I validate it says :
"you have not created a bootloader stage1 target device"
"you have not created a bootable partition"
this happens whether the /boot partition is formated in ext4 or EFI.

If I delete the /boot partition it simply says "failed to find a
suitable stage1 device".

How do I do get this to work ? I have to add that I have the same
problem when I try to install Fedora 23 vanilla.
