The folks at tecmint are in love with the command line. They will go through all kinds of contortions to use CLI even when GUI is much simpler and quicker.

@Jerry,

Why not revert the changes you did and set Linux as the default option in your Boot settings?

I was having a printer issue and changed the default to Windows. Now when I boot up the options screen does not show up and my system just goes straight into Windows. I would like to change the OS setting back to Linux as the default as I had before.

Any help on getting a boot options screen in Windows would be greatly appreciated.

Thanks

Before I started practicing according to your article, my machine’s partition system was as above. When I made the partition table by running “mklabel msdos“, then changed it to look like the below :

Command (m for help): p
Disk /dev/sda: 35 GiB, 37580963840 bytes, 73400320 sectors
Disk model: VMware Virtual S
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

/dev/sda4       34258944 73400319 39141376 18.7G  5 Extended

Command (m for help): w
The partition table has been altered.
Failed to add partition 2 to system: Device or resource busy
Failed to add partition 3 to system: Device or resource busy
Failed to add partition 4 to system: Device or resource busy

The kernel still uses the old partitions. The new table will be used at the next reboot.
Syncing disks.

What will happen after rebooting my laptop? Will I get my user login option ? will OS run in my computer ?

what is this warning?
