Windows 7: Bootable USB drive: problem with DiskPart utility

Windows 7
Bootable USB drive: problem with DiskPart utility

1. cmd
2. Diskpart
3. list disk
4. select disk 2
5. clean
6. create partition primary
7. select partition 1
8. active
9. format fs=fat32

Performing 9 fails:
"An object was again called before the first call was completed".
Retried with =ntfs, same msg.

Worse even, could not format as usual, because I "had no rights", although I am the administrator.

Purpose was to create a bootable usb stick as recovery instrument.
Anyone knows a better method?

And please:
How can I reuse my stick of 128Gb (not cheap...).

Disk Part Utility

Still learning Win 7, not to familiar with diskpart utility. Found this while searching for an answer for you. See if this link will help: Configure a USB flash drive to be a Windows 7 installation platform | Microsoft Windows |

5. type d: and then type cd\
4. type bootsect.exe /nt60 j: ( Which ever is your drive letter )
5. copy window 7 setup files to drive

Win 7 Ultimate x64

I just use pendrive linux's usb multi boot (Boot Multiple ISO from USB (MultiBoot USB) | USB Pen Drive Linux) Format the drive as fat32 open up the exe agree to the eula and select your drive. Then scroll all the way down to the bottom of list and there is a Windows 7/vista installer, just point it at you iso and you all set!

Hope this helps

Easiest is MS tool: Windows 7 USB/DVD Download Tool

But it can be picky about the ISO, so next easiest I've found is installing UltraISO trial: on File tab Open ISO, on Bootable Tab Write Disk Image, Format, Write. Boot under USB or HD.
