I installed Ubuntu on a USB drive and my partition table is

Disk /dev/sdb: 14.5 GiB, 15514730496 bytes, 30302208 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0xb643db4f

 Device     Boot    Start      End  Sectors  Size Id     Type
/dev/sdb1  *        2048 20537343 20535296  9.8G  83     Linux
/dev/sdb2       20539390 30300159  9760770  4.7G   5     Extended
/dev/sdb5       20539392 30300159  9760768  4.7G  82     Linux swap / Solaris

I created my kernel following by this link http://arjunsreedharan.org/post/82710718100/kernel-101-lets-write-a-kernel

when I add menuentry in etc/default/grub (grub.cfg)

menuentry 'mykernel' {
    set root='(hd1,msdos1)'
    multiboot /boot/mykernel-01 ro
}

and when run command

update-grub

this gives error

/usr/sbin/grub-mkconfig: 6: /etc/default/grub: menuentry: not found

How can I resolve this issue.

Does Ubuntu use grub-mkconfig command, what system is this? – George Udosen Mar 11 '17 at 17:33
I have windows10 on my ssd and Ubuntu 16.04 LTS on my 16 gb usb. – suleman Mar 11 '17 at 17:38

I changed it, any solution for this error. – suleman Mar 11 '17 at 17:43
please look at this article – George Udosen Mar 11 '17 at 18:02
I tried but this is not working. – suleman Mar 11 '17 at 18:10
I don't see quote marks around the root value. please do set root=(hd1,msdos1) – George Udosen Mar 11 '17 at 18:50
Let me rephrase that set root='hd1,msdos1' – George Udosen Mar 11 '17 at 18:54
I tried with all formats but not working. – suleman Mar 11 '17 at 18:58
