Hi! This was great help!

Just a couple of amendments that would help others trying khổng lồ install Windows 10 in 2020:

1 – after performing `clean`, some systems might benefit in using GPT partition instead of the mặc định MBR boot partition (for example if you want khổng lồ boot your PC in UEFI mode)

To convert khổng lồ GPT partition, run`convert gpt`

2 – Nowadays, Windows installer is slightly bigger than 5000 MB; might want to consider creating a partition larger than that (might be an overkill but I’ve sầu created an 8000MB partition)

Anyways, great guide!
