To backup removable NVME-stick i can do that within windows 10 here using Aomei Backupper.
But to recover i need bootable stick. First i must change bootorder in Bios.
I know when using save mode for other purposes external monitor is black and built-in is dead(forever).
I have to blindly navigate by finding out from a second ultrabook-also from acer but not the same model how to trigger keys.

1. Is this also the case when trying to navigate to bios.
2. external wifi-keyboard working? or do i have to use a cabled keyboard? will external screen show bios?

B: i could remove stick and clone and check if clone is working. simpler way if above is needed.
C: the weaker Acer Spin 1-111 had ssd built-in. so i must navigate to bios in any case.
Many thanks
Btw: By offering now Gorilla-Glass-screens on their new Swift 5 Acer is confessing their older screen were not reliable. The also have now semirugged Ultrabooks.
with Swift 5 i had a light drop at 45cm. also keyboard died. both after a 1 or 2 days-delay.
Spin 1-111 had FOUR heavy drops from 80cm only one hinge is halfdefective no more full 360 rotation. 1.25kg Swift 5 almost 1kg only.
