First I'll be up-front and say I was probably trying to run before walking, as I'm trying to build a HFSLIP CD of not just a Win 2000 but all 3. We have an original Win2000 MSDN CD which contains a boot loader that prompts for your choice of Professional, Server or Advanced Server. The CD contains sub-folders with installation sources for all 3. Files which are common to all 3 are hard-linked so the whole original CD is quite a bit less than 650MB. For each of the 3, I separately copied the I386 structure off the CD onto disc, ran the HFSLIP on it and then moved the patched I386 to a new folder structure. I then copied the other contents of the original MSDN CD into the new structure and re-linked all files which have the same name, size & checksum. I took the BOOT.BIN from the MSDN CD and burnt the ISO using the same mkisofs flags I found in the HFSLIP_60129.CMD file. No extra flags were needed to preserve the hard links. The resulting CD boots ok and offers the menu of the 3 versions. Upon selecting one (same problem on all 3) the normal Win 2000 installation proceeds until just after starting the GUI phase of setup. Then I get an error dialogue whose text is saved in SETUPERR.LOG I read through the web site again and the other documentation. The WU.TXT is taken from the host machine I used, not the intended target. The other log files are from the target. I've also included TREE.TXT which shows the folder structure on the CD. Note that when prompted in HFSLIP I told it the I386 was in "ENGLISH/WIN2000/PRO/" for example. Could anyone take a look at the attached logs and see if I've done anything wrong ? Many thanks.
