# Installation Troubleshooting #
|
|
|
|
## "An unknown error has occurred" error during installation ##
|
|
|
|
Some people have encountered this error message when trying to install Qubes on drives that already have data on them.
|
|
The solution is to exit the installer, wipe all data or delete all partitions, then restart the Qubes installation.
|
|
|
|
## Trouble installing from USB stick ##
|
|
|
|
If you are facing issues when booting using UEFI mode, see the [UEFI troubleshooting guide](/doc/uefi-troubleshooting/).
|
|
|
|
There are a variety of other problems that could arise when using a USB installation medium, and some of the issues can be fixed by doing one or more of the following:
|
|
|
|
* **Use a different USB drive:**
|
|
If possible, try several drives of different sizes and formats.
|
|
This determines whether the problem stems from the flash drive or Qubes installer.
|
|
Some laptops cannot read from an external boot device larger than 8GB.
|
|
If you encounter a black screen when performing an installation from a USB stick, ensure you are using a USB drive less than 8GB, or a partition on that USB less than 8GB and of format FAT32.
|
|
Note that the Qubes installation image is over 4GB, so it may not fit on a smaller USB.
|
|
If a machine can not boot from a bigger USB, it may be too old to run Qubes.
|
|
* **Verify your Qubes ISO:**
|
|
Errors will occur if the Qubes installer is corrupted.
|
|
Ensure that the installer is correct and complete before writing it to a flash drive by [verifying the ISO](/security/verifying-signatures/#how-to-verify-qubes-iso-signatures).
|
|
* **Change the method you used to [write your ISO to a USB key](/doc/installation-guide/#copying-the-iso-onto-the-installation-medium):**
|
|
Some people use the ``dd`` command (recommended), others use tools like Rufus, balenaEtcher or the GNOME Disk Utility.
|
|
If installation fails after using one tool, try a different one.
|
|
For example, if you are facing trouble installing Qubes after writing the ISO using Rufus, then try using other tools like balenaEtcher or the ``dd`` command.
|
|
In case the boot partition is not set to "active" after copying the ISO, you can use some other tool like `gparted` on a Linux system to activate it.
|
|
|
|
## Boot screen does not appear / system does not detect your installation medium ##
|
|
|
|
If the boot screen does not appear, there are several options to troubleshoot.
|
|
First, try rebooting your computer.
|
|
If it still loads your currently installed operating system or does not detect your installation medium, make sure the boot order is set up appropriately.
|
|
|
|
The process to change the boot order varies depending on the currently installed system and the motherboard manufacturer.
|
|
|
|
If **Windows 10** is installed on your machine, you may need to follow specific instructions to change the boot order.
|
|
This may require an [advanced reboot](https://support.microsoft.com/en-us/help/4026206/windows-10-find-safe-mode-and-other-startup-settings).
|
|
|
|
## "Not asking for VNC because we don't have a network" / "X startup failed, aborting installation" / "Pane is dead" error during installation ##
|
|
|
|
The boot mode in use may be causing these error messages.
|
|
Try to install after enabling both UEFI and legacy boot modes.
|
|
If that doesn't help, then disable one and try the other.
|
|
Visit the [UEFI Troubleshooting guide](/doc/uefi-troubleshooting/) if other errors arise during UEFI booting.
|
|
|
|
These errors may also occur due to an incompatible Nvidia graphics card. If you have one, follow the following instructions:
|
|
1. Disable secure/fast boot and use legacy mode
|
|
2. Enter GRUB, move the selection to the first choice, and then press the Tab key.
|
|
3. Now, you are in edit mode. Move the text cursor with your arrow key and after ``kernel=`` line, add:
|
|
|
|
nouveau.modeset=0 rd.driver.blacklist=nouveau video=vesa:off
|
|
|
|
If the above code doesn't fix the problem, replace it with:
|
|
|
|
noexitboot=1 modprobe.blacklist=nouveau rd.driver.blacklist=nouveau --- intitrd.img
|
|
|
|
For more information, look at the [Nvidia Troubleshooting guide](/doc/nvidia-troubleshooting/#disabling-nouveau).

## Installation freezes at "Setting up Networking" ##
|
|
|
|
If you are facing this problem on an Apple computer, check out the [Macbook Troubleshooting guide](/doc/macbook-troubleshooting/).
|
|
|
|
This issue occurs due to the network card, which may be missing some drivers or is incompatible with Qubes.
|
|
|
|
First, install all available drivers for the card.
|
|
You can install the drivers without internet access by first downloading them on another machine, then transferring them over to the current machine (e.g., with a USB drive).
|
|
|
|
If installing the available drivers does not help, disable the network card in the BIOS and perform the installation before re-enabling the card.
|
|
If this solves the issue, it confirms the PCI card is incompatible with Qubes.
|
|
In this case, you may want to consider replacing it with a network card of a different brand.
|
|
Broadcom cards are notoriously problematic with Qubes.
