#Create bootable usb windows 7 uefi install

In spite of using a std MBR for the USB, one can install via UEFI to a GPT disk. However, this is of little consequence as UEFI looks at the MBR/GPT and the EFI partition, see the Wikipedia entry on UEFI Booting You'll be able to configure the UEFI boot manager to load the Windows installer from the USB but the installer will search for files and data needed to perform the installation and it won't recognize the GPT USB, while it will find an MBR USB. You can use gdisk, or parted, and create a GPT USB, which will boot via UEFI. You cannot install Windows 7 from a GPT formatted USB.

#Create bootable usb windows 7 uefi 64 Bit

My config is 64 bit specific, you could try and change to accomodate a 32bit intall but there are many differences in filenames. I've been working on this for a few days, spare hour here and there and finally have a single USB, that will boot and offer installation of windows 7 and ubuntu. I'm presently using two USB sticks one for Windows, one for Ubuntu. Maybe the original question can be answered as well but since the goal was more on the install side the single boot UEFI USB seemed less important. It has taken a while and I've found the solution but we need to clean the question and answer. This doesn't work without errors, but as I worked with I uncovered that the goal was to use a USB to install both Windows and Ubuntu onto one hard drive, UEFI.

#Create bootable usb windows 7 uefi update

I'm working on an update to this question/answer. If I try to enter recovery mode (on HDD, where ubuntu is installed), keyboard seems to fail, mouse have light though. I then installed GRUB by booting the USB in recovery mode. I tried booting Ubuntu 11.10 Alternate in BIOS mode (Non-EFI), installed fine except I cannot install a boot loader. which is why I am delaying it to the last resort. that will mean I have to somehow backup all my data 1st. I feel I better not waste time and revert back to MBR soon. If I made a Ubuntu Desktop I will get cannot configure apt sources I am so lost, is Windows installed 1st the fault? I formatted & made a bootable USB for Ubuntu Alternate with UNetBootIn, and it failed too with same error of no available kernel. Next, I'll try using USB Startup Disk Creator to boot into a live system in EFI mode to try again Loaded efivars kernel module to enable use of efibootmgrД®lilo: Checking filesystem on /dev/sdc1.Д® lilo: 44298KB needed, 78781KB free, 42192KB to reuseД®lilo: Installing primary bootstrap /usr/lib/elilo/elilo.efi onto /dev/sdc1.Д®lilo: Installing /tmp/elilo.k8NWXX on /dev/sdc1.Д®lilo: Installing /vmlinuz on /dev/sdc1.Д®lilo: Installing /vmlinuz.old on /dev/sdc1.Д®lilo: Installing /initrd.img on /dev/sdc1.Д®lilo: Installing / on /dev/sdc1.Д®lilo: Updating EFI boot-device variable.ДЇatal: Couldn't open either sysfs or procfs directories for accessing EFI variables.Д®lilo: An error occured while updating boot menu, we'll ignore itДid sudo modprobe efivars got no output but got the same error, I think its because I am not bootted into EFI Ubuntu?

Extract Windows 7 & Ubuntu 11.10 iso's into Installer partition, 2 different folders.

Create 2 partitions on my USB (GPT, 100+MB FAT32 (/dev/sdc1, set boot flag), The rest FAT32, /dev/sdc2, for installs).

Then I need to configure GRUB EFI to load Ubuntu & Windows 7 install in EFI? How can I do these? I suppose I will format my USB as GPT, and install GRUB EFI on it (how?). I suppose I must use GRUB EFI instead? If theres no app like MultiSystem that creates a GRUB EFI Bootable USB, how can I create one myself? However, I am using GPT and Windows install needs to be launched in EFI mode to install on GPT system. I want to create a Bootable EFI USB to install Ubuntu & Windows 7 (maybe with utilities like PartedMagic).
