Installation freezes before displaying installer

-----------------------------------------------------------
|

|

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 here](/doc/uefi-troubleshooting/#change-installer-kernel-parameters-in-uefi) to edit the `[qubes-verbose]` section of your installer's `BOOTX64.cfg`.
|
||||
You want to comment out the `mapbs` and `noexitboot` lines.
|
||||
The end result should look like this:
|
||||
|
||||

||||

||||

~~~
|
||||
|
||||
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:

||||
|

Installation freezes before displaying installer / 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`.
|
||||
Consider this approach as a last resort, because it will make every Xen update a manual process.
|
||||
|
||||
1. Follow the [steps here](/doc/uefi-troubleshooting/#change-installer-kernel-parameters-in-uefi) to edit the `[qubes-verbose]` section of your installer's `xen.cfg`.
|

|
||||

cp -R /mnt/sysimage/boot/efi/EFI/qubes /mnt/sysimage/boot/efi/EFI/BOOT
|

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 steps](/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`.

There is a [common bug in UEFI implementation](http://xen.markmail.org/message/f6lx2ab4o2fch35r) affecting mostly Lenovo systems, but probably some others too.
|
||||
While some systems need `mapbs` and/or `noexitboot` disabled to boot, others require them enabled at all times.
|
||||
Although these are enabled by default in the installer, they are disabled after the first stage of a successful install.
|
||||
You can re-enable them either as part of the install process:
|
||||
|
||||
01. In GRUB menu<sup id="a1-1">[1](#f1)</sup>, select "Troubleshoot", then "Boot from device", then press `e`.
|
||||
02. At the end of `chainloader` line add `/mapbs /noexitboot`.
|
||||
03. Perform installation normally, but don't reboot the system at the end yet.
|
||||
04. Go to `tty2` (Ctrl-Alt-F2).
|
||||
05. Enable `/mapbs /noexitboot` on just installed system. This step differs between Qubes releases:
|
||||
|
||||
**For Qubes 3.1:**
|
||||
|
||||
06. Execute `mount | grep boot/efi` and note device name (first column). It should be something like `/dev/sda1`.
|
||||
07. Execute `efibootmgr -v`, search for `Qubes` entry and note its number (it should be something like `Boot0001` - `0001` is an entry number).
|
||||
08. Replace existing `Qubes` entry with modified one. Replace `XXXX` with entry number from previous step, `/dev/sda` with your disk name and `-p 1` with `/boot/efi` partition number):
|
||||
|
||||
efibootmgr -b XXXX -B
|
||||
efibootmgr -v -c -u -L Qubes -l /EFI/qubes/xen.efi -d /dev/sda -p 1 "placeholder /mapbs /noexitboot"
|
||||
|
||||
09. Compare new entry with the old one (printed in step 6) - it should only differ in additional options at the end, and look probably something like this:
|
||||
|
||||
Boot0001* Qubes HD(1,GPT,partition-guid-here,0x800,0x64000)/File(\EFI\qubes\xen.efi)p.l.a.c.e.h.o.l.d.e.r. ./.m.a.p.b.s. ./.n.o.e.x.i.t.b.o.o.t.
|
||||
|
||||
If instead it looks like:
|
||||
|
||||
Boot0001* Qubes HD(1,0,00000000...0,0x0,0x0)/File(\EFI\qubes\xen.efi)p.l.a.c.e.h.o.l.d.e.r. ./.m.a.p.b.s. ./.n.o.e.x.i.t.b.o.o.t.
|
||||
|
||||
then try passing `/dev/sda1` or `/dev/nvme0n1p1` or whatever your EFI partition is instead of `/dev/sda` and `-p 1`.
|
||||
|
||||
10. Now you can reboot the system by issuing `reboot` command.
|
||||
|
||||
**For Qubes 3.2 or later:**
|
||||
|
||||
11. Edit `/mnt/sysimage/boot/efi/EFI/qubes/xen.cfg` (you can use `vi` editor) and add to every kernel section:
|
||||
1. Perform installation normally, but don't reboot the system at the end yet.

2. Go to `tty2` (Ctrl-Alt-F2).
