How can I install RouterOS on a USB stick to be able to insert it on a PC and boot from it in routerOS environment? NetInstall will not do it…

Did you format the USB disk to Fat32?
I always use VMWare for this, boot the ISO and have USB flash device shared with the VM and it will install nicely…
Yes for some reason it wont do it …
I am going to try with vmware…
EDIT: What operating system do you chose in VMware ?
