[Tutorial] Working with additional 'drives'

Difficulty: ★★☆☆☆ 1. INTRODUCTION Microsoft Windows started its life as a graphical user interface on top of MS-DOS, a 16-bit single-user, single-tasking operating system that in turn originated as 86DOS, an unauthorized 16-bit rewrite (by Tim Paterson of Seattle Computer) of Digital Research’s originally 8-bit CP/M operating system. Both CP/M and MS-DOS were at the time developed for computers that did not support any other storage media than floppy disks. Considering this legacy, Microsof…

I’ll admit that I am highly confused. This flash drive I used to install window 11 on it, but for some reason. All the date on it was deleted. I was going to download it again, and make sure everything was right and then I ran into the problem that it cannot be mounted.

[Takakage]

Desktop environments typically provide a mechanism to mount USB flash drives automatically. What desktop environment are you using?

If you want to manually mount, you have to specify a mountpoint.

@man mount

The standard form of the mount command is:

mount -t type device dir

This tells the kernel to attach the filesystem found on device (which is of type type) at the directory dir.

If only the directory or the device is given, for example:

mount /dir

then mount looks for a mountpoint (and if not found then for a device) in the /etc/fstab file.

Or alternately

udisksctl mount -b /dev/sdc1

[Exodus]

 udisksctl mount -b /dev/sdc1                                                                                                                                                                       1 ✘

lsblk -f
gives some info on what is on /dev/sdc

Why not simply format it again since it is empty anyway?

You can use gparted, for example, or Gnome disks or some such name - or even fdisk and then mkfs directly

[Exodus]

That is something I have to do again anyway. I want to put the Window Os on it, so I can install it onto another PC that I have.

NTFS is not fully suppoted under Linux - you better use Windows itself to address any problems with that.

If you want to use the drive to install Windows, you have to follow the instructions that Microsoft gives to do that.
Or:
you could install Ventoy to that drive
and then simply copy the Windows .iso to it and can then boot from the drive, select the Windows .iso …
