They are cheap. I see you've got an eye for a bargain. You do right ..we have to shop around nowadays!! You must have some serious storage needs lol

Here's something for you. Plug in a USB stick, download the attachment, unzip, open Admin command prompt then run makeUSB.bat
NOTE: Command prompt must be run under the folder that you save makeUSB.bat
Save you some typing.
IMPORTANT: Make sure you select the correct USB disk #.

Attachment 171463

Here's the screen shot:

Thanks mate

If you want to insert all of the optional commands its:

diskpart
list disk
select disk #
clean
convert mbr
create part pri
select part 1
format fs=fat32 quick
assign
active
exit
exit

Straight through. Nothing in between. No exiting diskpart in the middle. No removing or re-inserting the flash drive. No rebooting the computer. No stopping for a cigarette break. Just straight through. The optional commands are in bold. You should not need them.

Hi Navy. Ive been trying to do the above this weekend without success. I followed the process exactly except I didn't use the Assign command and instead of quick format I performed a full format by removing "quick". Ive had two attempts with two different flash drives and each time I got the following error straight after the "Active" command was typed. "Diskpart has encountered an error. The system cannot find the file specified. See the system event log for more information". At the time of the error there are no errors shown in the system event log. All the other commands were successful.
I ran an SFC scan on my laptop to see if anything was wrong and checked for malware. Everything is fine. Can anybody tell me what Im doing wrong?
As regards the Active command..what should I do? I'm concerned now that because of this error my flash drive might be corrupted so I'm going to have to do all the commands again to be sure that everything has been done correctly.
I was wondering if I could do this instead
diskpart
list disk
select disk #
clean
convert mbr
Then..finish the rest of the process using Disk Management.
I'm thinking that I might not need the Active command because my system is UEFI boot but that doesn't answer why I'm having this error message.

Not everybody uses 250GB SSDs.

You get secure boot as well.

If users have large drives (>2.2 TB, you need to be using UEFI if drive has OS. In fact, if any drive is >2.2 TB, you need to make it GPT.

Just because you see no need for more than 4 Primary partitions, it depends if user decides to dual boot etc.
