For Non UEFI systems

Rufus use \isolinux
\stdmenu.cfg - TAB request or else boots to Ubiquity

Boot to: "try Ubuntu" for persistent USB instead of Ubiquity

For UEFI systems

E:\boot\grub\grub.cfg

Disable Disk Files Check

Tutor and explanation.
Google Query I searched with

Set timeout to 0

BoQsc commented 4 years ago

Research Grub "try ubuntu" menu item in grub.cfg and isolinux and make sure to replace Ubiquity with "try ubuntu" persistent.

BoQsc commented 4 years ago

Boot straight to the Try Ubuntu instead of Ubiquity choose menu

Copy isolinux boot line to grub

E:\isolinux\txt.cfg

file=/cdrom/preseed/ubuntu.seed initrd=/casper/initrd quiet splash

E:\boot\grub\grub.cfg Paste like this:

Sometimes when the Linux USB is shutdown by simply clicking shutdown button.
The Linux operating system does not shutdown and become stuck with this error:

[sdb] tag#0 access beyond end of device

IMG_20200511_180423

Note

sdb is the flash drive the error is on
Probably because the flashdrive format or Rufus is breaking and not showing the correct size of the flash drive.
This seems to be untrue, sometimes there is no such error. Rufus and Flash drive format is not part of the problem here.
Maybe sometimes Flash drive simply shutdown faster than the Ubuntu Linux?
And at the start of shutdown of Ubuntu, the USB flashdrives are being disconnected.
And before the shutdown is completed, the USB flash drive is inaccessible .
Therefore it shows error [sdb] tag#0 access beyond end of device
That would make sense since the Flash

[sdb] tag#0 access beyond end of device`

Probably happens when reached the memory last bit of the device's storage memory, or the device is empty and inaccesible.
