Hi, I've seen similar post on MDL, but it didn't answer my question. Can anyone tell me if it is possible to create a Bootable USB flash stick using Diskpart and a Win 7 SP1 DVD? What I want to do, if it is possible, is create a bootable USB flash stick using only Diskpart and copying the files from the Win 7 SP1 DVD to the bootable USB flash disk. If so, should I format it NTFS or Fat32? All I want to do is create an installable USB flash stick for Win 7 SP1 without a third part program. I would appreciate any and all help and/or comments. Thank You.
You could use diskpart for it but I would recommend to use the Windows7USBTool MS has. Create from your DVD an ISO and use that for to create the bootable USB Stick. If you use diskpart, keep in mind that in case you format to Fat32 the max. file size is 2 GB so you may will need NTFS format!
The command for diskpart are as follow: open a Command Prompt as Administrator run the following command all end with press Enter: diskpart list disk selectdisk ## (## No. of the USB Stick) clean create partition primary select partition 1 active assign format FS=NTFS quick (or format FS=FAT32 quick for FAT32) exit xcopy [source DVD/DIR]:\*.* /s /e /f [dest-drive USB-Stick] exit That should do the job. Note: I wouldn't use the parameter quick in format command, I would do a full format for to be sure the drive is clean!
FAT16: <2GiB (<4GiB with 64K clusters in NT IIRC) FAT32: <4GiB exFAT and NTFS have no practical limit.
You're right, sorry for my mistake. I should have written FAT instead of FAT32 because many (most older) sticks coming just FAT formatted and their limit of file size is 2.1GB
