Background My Dell Inspiron 1545 crashed and I had to reformat the hard disk. The Inspiron 1545 has no FDD and uses a SATA integrated controller. Internet posts recommend using nlite to preconfigure a custom OS disk to bypass the F6 problem during the XP installation. I downloaded the latest version of nlite, followed the instructions, and created an ISO file with XP and the required drivers for the 1545. Note that Dell did not include a XP recover disc, only one for Vista, and I will not install Vista. Also note that the preparation of the nlite 1545 installation disc was performed on a Dell Dimension 8400 running XP Pro SP3 with the latest security and critical updates installed. Problem I configured an unattended install, first using the original XP Pro with SP2 CD and the drivers for the 1545. The XP installation continues as expected until the creation of a partition and formatting the hard disk drive is encountered. I create a single partition on the 250Gb Seagate drive and format it using NTFS. (There is only one hard disk drive and one CD/DVD drive installed in the 1545.) The message that displays notes that "DRIVE 0" is being formatted, which is what I would expect. However, immediately after the format has completed, a message displays that "...files are being copied to drive E" (or words to that effect). The installation completes with no problems whatsoever. All the custom tweaks and component settings have been made, the drivers for the audio and video and NIC installed, everything is perfect... Except the system hard disk drive has been designated drive "E" for some reason. Unfortunately the drive letter designator for the system drive cannot be changed using any software that I've been able to find. Troubleshooting I have performed the reconfiguration of nlite a number of times using first the standard disc with SP2. I also tried a number of variations to the nlite installation configuration using SP3, including or excluding custom components and tweak settings, etc. All told I've performed six installations on the Dell 1545 using nlite and each results in an install to drive "E". Prior to each installation I use Seagate's DiscWizard to wipe the HDD on the 1545. I originally selected nlite because of the need to load the SATA/SCSI drivers during the XP installation. I located a post that suggested changing the BIOS setting of the SATA controller from ACHI to ATA which eliminates the original F6 problem. In other words, with ATA enabled, the original Microsoft XP Pro with SP2 installs with no problem. During the hard disk drive partition and format process DRIVE 0 is partitioned and formatted and the XP system files are copied to DRIVE "C" as they should be! Just as a test, I performed another wipe disk and attempted to reinstall XP from the nlite disc with ATA still enabled in the BIOS. Same problem... XP designates the 1545's HDD as drive "E" instead of "C". As noted I don't need to use nlite any longer to get my laptop up and running but I'm really curious as to why I seem to be the only one having this problem. Any ideas?
