Hi Use Nero to make vLite bootable UDF's, but first you need to copy the boot image from the vista CD using isobuster. Insert the original vista cd and (make a note of the title/name of the cd) e.g. WXPVLK_OEM or similar. Then open with isobuster. When you have it opened, look to the left and select the (bootable cd) tab, usually the blue tab. After selected you will see 2 files in the window on the right, (miscrosoft.img and bootcatalog) Select those 2 files and extract them to a folder on your desktop. Those are the 2 files you need to tell nero to burn to the disc also to make it bootable. I keep my vLite and nLite preinstalls in folders on my desktop when i am working with them and i keep also an XP and Vista boot_img folder next to them on the desktop but not in with my preinstalls, so keep the folders seperate. (2 folders one for your vista/vLite files and one for the boot image files. NERO: Start up nero in standard mode not the smart start and select (DVDROM / boot) After selected the first tab to open up is the 'boot' tab. (source of boot image data) Select 'image file' and browse to the folder on your desktop where you copied the microsoft.img from the vista cd. Next in the dropdown select (all files) not .ima file or you will not see the microsoft image. default is set to ima. After you have the microsoft.img file chosen, next in the bottom half of the window check the 'advanced' box. Set 'kind of emulation' to (none) Set 'number of loaded sectors' to (4) default is 1. the other settings on this tab are ok. Next go to the 'label' tab and choose to name manually, and reneme to the same name as the Vista cd like above. Next on the 'misc' tab select (cache files under 64k) Click on 'burn' and your ready to go.. just browse to the folder where you put your tailored vista files and burn them. Good luck... and look ma' no command lines
