1/ win10 64 bits installed on a laptop (partitioned as sda1(I believed win10, while I believe sda3 win10 recovery) and data on sda5, sda6, sda7)
2/ Manjaro 18 rc3 XFCE booted from an USB key
3/ an USB external drive where it had previously Manjaro 17.1.10 XFCE
Booting from the USB key, I installed Manjaro 18rc3 on what I believe the partition of Manjaro 17.1.10 (I presumed I failed and Grub installed on the internal HDD and not on the usb external one, but this is only an assumption)
Reboot and I swith to
error: no such device : 5bc...
error: unkown file system
I tried How to Fix error: unknown filesystem grub rescue in Windows 7/8.1/10 (Advanced Tutorial) https://www.youtube.com/watch?v=a8UuIBdMh4M
But apparently, all ls (hd0,msdosX) leads to "Filesystem is unknown"
Rebooting from the usb key, I see with Thunar that my win10 partition is there with all its files, maybe, but I'm not sure the partition has change name to "TI30876100A"
How to fix so that:
- my laptop starts with win10 (there is no manjaro install on the internal HDD)?
- subsequently, starts Manjaro from the external USB hdd when I plug it?
