Windows 10: Can’t delete/format the selected partition when installing win10 from usb

I am trying to reinstall win10 to my laptop because my laptop cant start. I downloaded the ISO directly from Microsoft onto a usb pen.


When it asked me where to install windows, I selected the biggest one directly but then it said windows couldn’t format a partition on disk 0. Then I tried to delete or format the existed partition and it said We couldnt delete the selected partition Error 0x8007045d.


So i cant delete and create new partition as what other solutions suggest...... HELP...

How To Format A Write Protected Flash Memory ?

¿You already tried this one?...

Run CMD


1. diskpart
2. list disk

Then in the 3º step, put the correct number of disk in the list for the usb flash (if it's listed in disk 3, then you'll have to write select disk 3).

2. select disk #
3. clean
4. create partition primary
5. select partition 1
6. active
7. format fs=fat32
8. assign
9. exit

with that commands you will format the flash drive in fat32, if you have a large drive you can select also "format fs=ntfs" in step 7.

good luck!
