I tried to make a clean Vista installation from DVD I made with 1.1.6 Final vLite - nothing removed, just SP1 and post-SP1 hotfixes included and it turned that disc is not bootable! It is 32 bit Polish Vista Business. It was burned from vLite on good media using double speed recording. Disc is readable, everything seems to be ok, so I tried to look at it using ISOBuster. ISOBuster shows that it is in fact bootable DVD, but when I looked closer at bootsector (located at LBA 282) it was filled with 00 bytes. What had I done wrong? Is it any way to make vLite use my provided bootsector (I can rip it off original pre-SP1 Vista DVD using ISOBuster)? EDIT: I forgot to say, that on vLited DVD Bootable Disc contains only BootCatalog.cat (2048 bytes, all 0x00h). On my OEM disc there are two files BootCatalog.cat (2048 bytes, with Microsoft Corporation string in the beginning followed by 0x00h bytes) and Microsoft Corporation.img (2048 bytes).
