Fast way to convert some folders on your host machine to .iso files so that you can mount them as CDs on your guest OS.
This is a way of how to do it.
Save code from New-ISOFile/New-ISOFile.ps1 at main · TheDotSource/New-ISOFile as New-ISOFile.ps1
on your computer. Check if the code source is safe.
Open Windows command prompt under a normal user
Navigate to the folder where you've saved New-ISOFile.ps1
using the command prompt.
Run this command:
powershell -ExecutionPolicy Bypass -noprofile -c "& { . .\New-ISOFile.ps1; New-ISOFile -source 'C:\Downloads\folder_you_want_to_convert_to_iso\' -destinationIso C:\folder_not_requiring_admin_priveleges_to_save_into_it\testiso.iso }"
Now, you can launch qemu so that your guest OS see that .iso file as a mounted CDROM.
