By default Linux distros are unoptimized in terms of I/O latency. So, here are some tips to improve that.

Most apps still don't do multi-threaded I/O access, so it's a thread-per-app which makes per-app speed always bottlenecked by single-core CPU performance (that's not even accounting for stuttering on contention between multiple processes), so even with NVMe capable of 3-6 GB/s of linear read you may get only 1-2 GB/s with ideal settings and 50-150/100-400 MB/s of un/buffered random read (what apps actually use in real life) is the best you can hope for.

All writes are heavily buffered on 3 layers (OS' RAM cache, device's RAM cache, device's SLC-like on-NAND cache), so it's difficult to get real or stable numbers but writes are largelly irrelevant for system's responsiveness, so they may be sacrificed for better random reads.

The performance can be checked by:

`fio --name=read --readonly --rw={read/randread} --ioengine=libaio --iodepth={jobs_per_each_worker's_command} --bs={4k/2M} --direct={0/1} --num

Installing Windows using CMD. (UEFI and BIOS Supported)

Guide created by Andrew Lee

Note that this guide does not go into detail, it's just providing the commands to install Windows.

Be cautions when doing this when dualbooting, please backup any existing data or you will lose them all.

Open CMD

First open CMD by pressing the following keys after booting into setup: Shift + F10

Instructions to Update the BIOS/UEFI for an HP Laptop on Linux

To update the BIOS/UEFI firmware requires HP-specific files in the EFI System Partition, also referred to as ESP.

On a Linux system, the ESP is typically mounted on /boot/efi or /efi. Whithin you should also find a EFI directory, e.g. /boot/efi/EFI or /efi/EFI. This article assumes that the ESP is mounted on /efi and that the /efi/EFI directory exists. You can replace that with the mount point your system uses.

The HP-specific files are located in /efi/EFI/HP or /efi/EFI/Hewlet-Packard. These files typically come preinstalled in HP Windows PCs. If you have these files you could skip Install HP-specific files.

	# It sets up a separate Proton prefix for each executable to avoid conflicts.
