Get invalid partition table while trying to install win from usb

Well, Thanks for your help.
I manage to get my hand on a cd-drive so I used my win DVD.

Thanks anyway..

The method which always works for me is using the trial version of UltraISO Software To Create Bootable USB Flash Drive.

Previously I always used Universal USB Installer which worked great for several years but now is blocking HD boot when the stick remains plugged. May be the Linux coding.

Since this will be found for years in Google searches please report back results trying these.

I have Win 7 on a USB. Used it to install on my laptop, install went smooth as silk.
Then put the same USB in my desktop, change boot sequence to boot USB first, and i get black screen with error message "invalid partition table".

Any thoughts guys?

Win7 should be on this drive ok, if it installs properly on another computer right? Or might my desktop need the USB to be formatted differently?

Stuck,
Mike

Is the difference UEFI BIOS vs. Legacy BIOS? Because if so it needs UEFI Bootable USB Flash Drive - Create in Windows using Option 1.

If not then check over all the settings in BIOS to enable Legacy USB, all USB choices, set HDD first to boot, boot stick using one-time BIOS Boot Menu key under REmovable, USB by name, or HDD to see USB choice.

I know this thread is a bit old, but am posting to help others who are looking for help.

So, I had the identical error, except I was creating a multiboot USB drive with several bootable OS ISOs copied by YUMI. I have a SanDisk 16GB USB3 USB drive.

By following the instructions earlier posted in this thread, I was able to use DiskPart in a CMD window to properly format with FAT32 and set this partition as Active. After adding the ISOs through YUMI again I was able to successfully boot in to the boot loader.

I believe the root issue in this entire thread is that the said USB drive does not have an ACTIVE partition, which I believe will NOT be bootable. I think this because before I formatted with DiskPart, I viewed the details of the partition I was trying to boot from, and it was NOT ACTIVE.

Hope this helps someone...

This actually corrected my issue with being able to install via usb. I looked at all the methods. Everythings was set up i just needed to change to UEFI. I'm on windows 7. No other options though, just choose UEFI.

The same here, couldnt launch Windows 10 setup due to "invalid partition table" error. My solution (tested on Gigabyte GA-P965-s3, Award bios):
1. from Windows format your USB stick to FAT32 (default allocation size)
2. paste your Windows 10 image in UltraISO, choose "USB-HDD+" as writing method
Notice: I got Windows 10 image via Media Creation Tool wherein I chose exactly single bit edition (x64 in my case) instead of "both x64/x86 edition", thereby created ISO weighs less than 4gb so it doesn't create any problems for old motherboards
3. after successful writing plug your USB stick into the rear usb port of your motherboard instead of usb port on front panel
4. enter BIOS settings -> Advanced settings -> Hard disk boot priority, move USB-HDD to the top of the list, save changes
5. exit bios, press F12 to enter list of boot sources, select "USB-HDD"
6. after installation your PC will reboot automatically, after then go to bios settings -> Hard disk boot priority, move your normal HDD to the top of list, save changes and exit bios, installation will be automatically continued from your normal HDD
