The following instructions are valid for **Qubes OS R4.0 legacy mode**
|
||
|
|
and **Qubes OS R4.1 legacy and UEFI modes**. For **Qubes OS R4.0 in UEFI mode**, there is no GRUB, so manual boot from another operating system
|
||
|
|
is needed.
|
||
|
|
|
||
|
|
In several cases, there is a need to prevent ``autostart=True`` for
|
||
|
|
qubes on boot. For example:
|
||
|
|
|
||
|
|
- ``sys-usb`` was enabled, but the only keyboard is attached via USB,
|
||
|
|
and the ``qubes.InputKeyboard`` service is disabled.
|
||
|
|
|
||
|
|
- A PCI device assigned to an autostarting qube crashes the system
|
||
|
|
(e.g., a GPU or RAID controller card).
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
To address this, there is a ``qubes.skip_autostart`` option for the
|
||
|
|
kernel command line. You can use it at the grub boot menu.

Press the ``E`` key on the first prompt (or your custom prompt). Then,
|
||
|
|
press the down arrow key multiple times to reach the line starting with
|
||
|
|
``module2``.

||

|
||
|
|
|
||
|
|
Append ``qubes.skip_autostart`` to the end of this line (generally after
|
||
|
|
the ``rhgb quiet`` options).
|
||
|
|
|

|
||
|
|
|
||
|
|
Press ``Ctrl+X`` to boot with the edited GRUB entry. The boot will
|
||
|
|
proceed as usual from here, except that no qube will be autostarted.
