Not so important notes

Reinstall Windows

https://support.hp.com/tw-zh/document/c06177099 I first created Win10 Pro USB with drivers, but it couldn't detect product key in this device. I created again without drivers, this time it can reinstall Win10 Pro properly.

VirtualBox install WIndows 10 with OEM key

Fetch OEM key https://www.medo64.com/2020/10/windows-product-key-in-virtualbox-bios/

cat /sys/firmware/acpi/tables/MSDM > msdm_table.dat
vboxmanage setextradata "VMName" "VBoxInternal/Devices/acpi/0/Config/CustomTable" /msdm_table.dat

Didn't proceed afterwards

Convert HP Win10 Pro USB to iso (doesn't work)

Virtualbox doesn't support usb boot out of box, and I think it's better to create an ISO and keep it anyway.

Insert USB, mount it

cd ~
mkdir usb
lsblk
# Find your disk device id, assume it's sda1
sudo mount /dev/sda1 ~/usb

Getting this because my USB is damaged and is permanately in read mode, but seems mounted successfully

Error opening '/dev/sda1' read-write
The disk contains an unclean file system (0, 0).
The file system wasn't safely closed on Windows. Fixing.
Could not mount read-write, trying read-only

Convert to iso

sudo apt install genisoimage
mkisofs -o ~/VirtualBox\ VMs/Windows10Pro_OEM/HP_Win10Pro_Install_USB.iso -allow-limited-size  ~/usb
# check files there
sudo mount -o loop ~/VirtualBox\ VMs/Windows10Pro_OEM/HP_Win10Pro_Install_USB.iso ~/iso/
sudo umount ~/iso

Use default installation, full disk encryption. That means Win10 Pro and HP recovery partition is erased as well

Hibernation support

Based on: https://pop-planet.info/forums/threads/guide-to-hibernate-answer-is-a-guide.426/#post-4358

# hibernation UEFI Bios systemd-boot kernelstub swapfile

# Create swapfile
fallocate -l [N]G /swapfile # [N] = swapfile size in GB
chmod 600 /swapfile
mkswap /swapfile
swapon /swapfile

# Edit fstab
# Add
/swapfile none swap defaults 0 0

# Remove default swap:
sudo swapoff -a
sudo cryptsetup remove cryptswap
# edit `/etc/fstab`, comment the line mentioning cryptswap
# edit `/etc/crypttab `, comment the line mentioning cryptswap

# checking the status of the swap, it should have been disabled
sudo cryptsetup status /dev/mapper/cryptswap
# /dev/mapper/cryptswap is inactive.

# To check swap status, use:
> swapon --show

# The following command may be used to identify swap_file_offset:
filefrag -v /swapfile | awk '{ if($1=="0:"){print $4} }'
# ==> the physical value where the file starts = 241664

# kernel boot parameter:
kernelstub -a "resume=/dev/mapper/data-root resume_offset=swap_file_offset"

# Add to /etc/initramfs-tools/conf.d/resume the same line kernel boot parameter

sudo update-initramfs -u
sudo update-initramfs -c -k all
> reboot

# Test hibernate
sudo systemctl hibernate

sudo cryptsetup remove cryptswap1 doesn't work, mine is cryptswap
swapfile is 64GB since that's the maximum allowed for this device.

Britness hot key doesn't work

This is because I have installed hot key driver in Windows, this somehow changes bios state and can only be erased by a power reset

IME

Built-in ibus support, but I can't get jp input to work so installed fcitx instead https://blog.jixun.moe/pop-os-21-04-install-fcitx-rime

TC: fcitx-chewing, JP: fcitx-mozc CHanged short key to Ctrl+Space: on/off and Ctrl+Shift: cycle through

Looks like it's possible to get fcitx5 https://gist.github.com/kuang-da/3e77389965cd24e726db545c690a4c1d haven't tried yet, fcitx4 works fine so probably won't bother

IME not working in Spotify https://bbs.archlinuxcn.org/viewtopic.php?id=10580 no fix for now (sad)

Need to enable XML edit from preference

When editing, the following must be edited in one go, otherwise they'll be discarded on saving:

Not sure if double quotes are required. Make sure boot options have CDRom selected and is the first boot order.

sudo apt-get install samba cifs-utils

Follow the guide to configure the folder on linux side 1.

mkdir /vm_shared
sudo chmod 0777 /vm_shared

sudo vim /etc/samba/smb.conf

[vm_shared]
  comment = VM SHARED FOLDER
  path = /vm_shared
  read only = no
  guest ok = yes

/etc/init.d/smbd restart

Once it's done, go to windows cmd, tpye ipconfig /all, check gateway ip of ethernet, then go to

\\192.168.1.1

to access vm_shared folder
