Installation freezes before getting to Anaconda (Qubes 4.0)
|
||||
-----------------------------------------------------------
|
||||
|
||||
Some systems can freeze with the default UEFI install options.
|
||||
You can try the following to remove `noexitboot` and `mapbs`.
|
||||
If you have an Nvidia card, see also [Nvidia Troubleshooting](/doc/nvidia-troubleshooting/#disabling-nouveau).
|
||||
|
||||
1. Follow the [steps above](/doc/uefi-troubleshooting/#change-installer-kernel-parameters-in-uefi) to edit the `[qubes-verbose]` section of your installer's `xen.cfg`.
|
||||
You want to comment out the `mapbs` and `noexitboot` lines.
|
||||
The end result should look like this:
|
||||
~~~
|
||||
[qubes-verbose]
|
||||
options=console=vga efi=attr=uc
|
||||
# noexitboot=1
|
||||
# mapbs=1
|
||||
kernel=vmlinuz inst.stage2=hd:LABEL=Qubes-R4.0-x86_64 i915.alpha_support=1
|
||||
ramdisk=initrd.img
|
||||
~~~
|
||||
2. Boot the installer and continue to install as normal, but don't reboot the system at the end when prompted.
|
||||
3. Go to `tty2` (Ctrl-Alt-F2).
|
||||
4. Use your preferred text editor (`nano` works) to edit `/mnt/sysimage/boot/efi/EFI/qubes/xen.cfg`, verifying the `noexitboot` and `mapbs` lines are not present.
|
||||
This is also a good time to make permanent any other changes needed to get the installer to work, such as `nouveau.modeset=0`.
|
||||
For example:
|
||||
~~~
|
||||
[4.14.18-1.pvops.qubes.x86_64]
|
||||
options=loglvl=all dom0_mem=min:1024M dom0_mem=max:4096M iommu=no-igfx ucode=scan efi=attr=uc
|
||||
~~~
|
||||
5. Go back to `tty6` (Ctrl-Alt-F6) and click `Reboot`.
|
||||
6. Continue with setting up default templates and logging in to Qubes.

Installation freezes before getting to Anaconda / disable EFI runtime services
|
||||
------------------------------------------------------------------------------
|
||||
|
||||
On some early, buggy UEFI implementations, you may need to disable EFI under Qubes completely.
|
||||
This can sometimes be done by switching to legacy mode in your BIOS/UEFI configuration.
|
||||
If that's not an option there, or legacy mode does not work either, you can try the following to add `efi=no-rs`.
|
||||
|
||||
1. Follow the [steps above](/doc/uefi-troubleshooting/#change-installer-kernel-parameters-in-uefi) to edit the `[qubes-verbose]` section of your installer's `xen.cfg`.
|
||||
You want to modify the `efi=attr=uc` setting and comment out the `mapbs` and `noexitboot` lines.
|
||||
The end result should look like this:
|
||||
~~~
|
||||
[qubes-verbose]
|
||||
options=console=vga efi=no-rs
|
||||
# noexitboot=1
|
||||
# mapbs=1

|
||||
ramdisk=initrd.img
|
||||
~~~
|
||||
2. Boot the installer and continue to install as normal, until towards the end when you will receive a warning about being unable to create the EFI boot entry.
|
||||
Click continue, but don't reboot the system at the end when prompted.
|
||||
3. Go to `tty2` (Ctrl-Alt-F2).
|
||||
4. Use your preferred text editor (`nano` works) to edit `/mnt/sysimage/boot/efi/EFI/qubes/xen.cfg`, adding the `efi=no-rs` option to the end of the `options=` line.
|
||||
For example:
|
||||
~~~
|
||||
[4.14.18-1.pvops.qubes.x86_64]

mv /mnt/sysimage/boot/efi/EFI/BOOT/xen.efi /mnt/sysimage/boot/efi/EFI/BOOT/BOOTX64.efi

7. Continue with setting up default templates and logging in to Qubes.

||||
|

Whenever there is a kernel or Xen update for Qubes, you will need to follow these [other steps above](/doc/uefi-troubleshooting/#boot-device-not-recognized-after-installing) because your system is using the fallback UEFI bootloader in `[...]/EFI/BOOT` instead of directly booting to the Qubes entry under `[...]/EFI/qubes`.
