RTL8812BU VS Ventoy

RHEL 8 is a 4.18 kernel, this driver might work as it is tested with 4.15. Realtek drivers are known to be annoying, unfortunately they are in a ton of USB dongles because they are so cheap.

sudo apt update sudo apt install -y dkms git bc git clone -b v5.6.1 https://github.com/fastoe/RTL8812BU.git cd RTL8812BU make sudo make install sudo reboot

You bought an adapter with no linux support. A short google search shows that thing uses a Realtek RTL8812BU chip. It looks like there is a 3rd party driver made for linux at https://github.com/fastoe/RTL8812BU but it requires you to clone and compile it.

Later, wife noted wifi was not as good in particular part of house so installed a RTL8812BU wifi adapter using driver from https://github.com/fastoe/RTL8812BU.

Is it https://www.brostrend.com/products/ac3? I ask because I bought https://www.ebay.com.au/itm/284231856690 and followed instructions here, https://github.com/fastoe/RTL8812BU - instructions are different depending on kernel. Yours and mine use the same chipset.

The sophisticated driver from https://github.com/fastoe/RTL8812BU expects the mentioned kernel image vmlinux in the standard location

I downloaded this driver: https://github.com/fastoe/RTL8812BU/tree/v5.8.7 and hoped to easily install it offline, but it didn't work. Terminal tries to download metadata, but obviously it's not possible without internet. Compiling it gave also an error, if I remember correctly it said that it couldn't find anything in temp build folder? DKMS can't be installed either. I also tried to download it on my phone and move it then to Fedora (like I did with the WiFi driver), but it wasn't possible to install it because of too many dependencies that I have no access to...

sudo apt update sudo apt install -y dkms git bc git clone -b v5.6.1 https://github.com/fastoe/RTL8812BU.git cd RTL8812BU VER=$(sed -n 's/\PACKAGE_VERSION="\(.*\)"/\1/p' dkms.conf) sudo rsync -rvhP ./ /usr/src/rtl88x2bu-${VER} sudo dkms add -m rtl88x2bu -v ${VER} sudo dkms build -m rtl88x2bu -v ${VER} sudo dkms install -m rtl88x2bu -v ${VER} sudo modprobe 88x2bu sudo reboot

Had no WIFI option at all. Downloaded this driver (RTL8812BU v5.6.1, for 5.10 kernel) on my phone and connected it then to my PC, so I can install it: https://github.com/fastoe/RTL8812BU/tree/v5.6.1

Ventoy is an open-source tool to create a bootable USB drive for ISO/WIM/IMG/VHD(x)/EFI files. Using Ventoy, we can create live USB for multiple distros in one flash disk. This is a revolutionary feature compared to other tools, e.g., Etcher, Rufus, etc, that can only create one live USB at a time. This tool is so important. Don't call yourself a distro hopper if you don't know this tool.

I'm thinking you mean Ventoy? They say they can load vhd and img files, though I've only tried ISO's myself.

I faced it too. There is a PR on the ventoy GitHub repository that fixes Proxmox boot.

> While this works, I find this method a bit tedious to use, at least compared to Ventoy [0].

I find ventoy more tedious, because you can't use it on your hard drive with a sane partitioning scheme.

The only reason is because of how the ventoy detection hardcode the partition boundaries in its checks, and it means Ventoy can only run with the partitions set in a way that may lead to alignment issues like write-amplification: I've detailed that in https://github.com/ventoy/Ventoy/issues/1342

Ideally I'd have a 10G partition after the EFI (or it could even be the EFI itself) with a few ISOs for rescue purposes + a UEFI entry to avoid having to use a bootable USB, but that's not possible with Ventoy unless I accept Ventoy choices of partition boundaries:

                (pMBR->PartTbl[0].StartSectorId != 2048 ||

I downloaded and made a bootable USB Ventoy (https://www.ventoy.net) with its Windows GUI app in my updated 64-bit W10 Pro PC. However, I couldn't seem to get VirtualBox v7.0.12 to boot it. I read VirtualBox can boot from bootable USB flash sticks so it should work. Am I missing something?

So, yes. The installer will need to install grub to that first partition. You can install ventoy to a usb drive, put a windows iso there and your q4os iso. In case you mess up big time, you can reinstall windows.
