Hello.. I have RDP thinbook 1450 thinbook. It has 32 gb emmc storage which contains window 10 32 bit. In my thinbook there is no option for boot another device or secure boot. So i am trying to convert partition gpt to mbr. Via easus partition master pro. But after converting my system was not booting. It was stucked at shell script and my system was not starting. Please solve this problem.

I do not think any of the RDP Thinbooks can boot EXCEPT in EFI mode. And EFI REQUIRES GPT partition table.

If you have converted your partition table already to MBR, that may be why it is not booting. Nothing I know can be done in UEFI firmware / BIOS to fix it. You will need to convert the partition table back to GPT - perhaps using some sort of live boot USB medium.

You could try my pre-built ISO files to create a live-boot Ubuntu disk, but I do not know whether / how to convert a MBR partition table to GPT without losing all data on the disk.

Sorry for the bad news - maybe you should have been askingthe right questions BEFORE changing your partition table.

If you DO want to use a live-boot ISO such as my pre-built Ubuntu ISOs, you will NEED to turn off Secure Boot in the UEFI firmware.

I think live cd may be not working cause in bios there is no option for usb boot or any other boot.

Although i will try. Can u send me a link for download that. I have another slot of hdd in laptop. Can i use it for another boot.

Here is the link to Ubuntu Xenial Xerus 16.04. The link is also on my RDP-Thinbook-Linux main page, along with instructions to validate ISO after downloading.

You cannot use a Live CD ISO image to write onto a hard disk. They are just different formats. You could create a bootable disk and use a DIFFERENT machine to install onto a hard disk and then switch the hard disk to this RDP laptop to try booting. Problems with this:

The Live CD ISO is designed to boot either in an MBR (legacy BIOS) machine OR a GPT EFI machine, whether the EFI Loader expects a 32-bit or a 64-bit EFI Image
