Gpt partition recovery

The whole point was to do a clean install on a clean drive, partitioned the way I like.For the benefit of future web hikers, I will go ahead and answer my own question.HOW TO CREATE A GPT PARTITION TABLE AND REINSTALL WINDOWS 8 WHEN THE RECOVERY WILL NOT WORK:1. Boot up from the recovery USB drive and go to the command prompt.2. At the command prompt, enter the following (note that this will give you a 150 GB Windows partition and a big user data partition; the data partition can be omitted if desired):diskpartselect disk 0cleanconvert gptcreate partition primary size=300format quick fs=ntfs label="Windows RE tools"assign letter="T"set id="de94bba4-06d1-4d40-a16a-bfd50179d6ac"gpt attributes=0x8000000000000001create partition efi size=260format quick fs=fat32 label="System"assign letter="S"create partition msr size=128create partition primary size=153600format quick fs=ntfs label="Windows"assign letter="W"create partition primaryshrink minimum=15000format quick fs=ntfscreate partition primaryformat quick fs=ntfs label="Recovery image"assign letter="R"set id="de94bba4-06d1-4d40-a16a-bfd50179d6ac"gpt attributes=0x8000000000000001exit3. Now you should be out of Diskpart but still at the command prompt. Copy the recovery images to the recovery partition. Your recovery USB will probably be drive C, and the images will be several install.swm files in the Sources directory. Copy them to drive R. Like this:c:cd sourcescopy *.* r:4. Apply the images to the Windows partition:dism /apply-image /imagefile:install.swm /swmfile:install*.swm /index:1 /applydir:W:\5. Copy the Windows RE tools to the Windows RE partition:md T:\Recovery\WindowsREw:cd windows\system32\recoveryattrib winre.wim -h -s -r [use this line only if the next line fails]copy winre.wim t:\recovery\windowsre\6. Copy the boot files to the System partition:bcdboot w:\windows7. At this point, Windows will boot up, but will look funny. You can now do a Reset Your PC without getting the message about a missing partition, and everything will be back to normal!FOR FURTHER READING: I have more time, I plan on making another attempt to get it to work in MBR instead of GPT
