Cannot install windows on MBR parition table
Hi I have a Inspiron 5555 that needed to be wiped. I deleted all the partitions and went to create one partition but I get the following error when I try and install from USB:
Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks.
Any idea what I need to do? Sounds like maybe the drive is protected?

No not drive protected at all. Try the steps in the following video and you should be good to go.

Deleting the partitions doesn't remove the designated partition layout. You need to completely un-initialize the disk. To do that, open Command Prompt in Windows Setup by pressing Shift+F10 (you might need to hold the Fn key as well depending on the keyboard's default mode for handling the F keys) and then enter the following:
diskpart
list disk
select disk X (replace X with the number for your SSD based on the output of "list disk" above)
clean
If you see an error, enter the "clean" command again. Once you see that the disk has been successfully cleaned, proceed through the Windows Setup wizard and you should be set.

Note "clean" will erase all data on the drive selected. ...Even if you selected the wrong disk!
When using it I double-check to make sure I've got the right drive. Note only the drive capacity/size is shown, not the drive model number or anything - easy to get them confused. I'll even remove drives with important data before using diskpart.
To double check I've got the right drive number I usually do "list disk" again after "select disk X". The selected disk shows up with an asterisk (*) to the left of it. This forces me to slow down and think before doing the "clean". Only then and when I'm sure I'm essentially erasing the right disk do I type and run "clean".
So, the sequence is like:

The disk is not protected. There are many ways to solve the problem, but the most direct way is converting MBR to GPT disk, as it mentioned “Windows can only be installed to GPT disks”. To convert MBR to GPT, you can enter Disk Management by right clicking This PC/My computer>Manage>Storage>Disk Management. Then Right click every partition on the MBR drive, select delete volume to make the drive without any partitions(showing unallocated), finally right click the empty disk and select "convert to GPT Disk" and follow the hints to finish the conversion.
If the "Convert to GPT Disk" option is greyed out, you can use a professional MBR to GPT converter.

The OP is trying to complete the Windows Setup process. Your steps are only possible from a live Windows environment. Disk Management isn't available in Windows Setup.
