According to the installation guide, I should be able to do a hard drive installation from sources on a USB drive: (from http://docs.fedoraproject.org/install-guide/f7/en_US/sn-installing-from-harddrive.html) "Once you have booted your computer, you may use ISO image files of the Fedora discs to continue the installation process. The ISO files must be located on a hard drive that is either internal to the computer, or attached to the machine by USB." My experience, however, is that it does not work; when I boot into the installer and am prompted for sources, my USB drive is not among the options presented as source partitions. My suspicion is that usb-storage is not loaded; if I unplug and plug my drive, the kernel messages are (approximately): usb 5-8: USB disconnect, address 5 usb 5-8: new high speed USB device using ehci_hcd and address 6 usb 5-8: configuration #1 chosen from 1 choice Normally, however, plugging in my drive results in the following messages: usb 5-8: USB disconnect, address 5 usb 5-8: new high speed USB device using ehci_hcd and address 6 usb 5-8: configuration #1 chosen from 1 choice scsi3 : SCSI emulation for USB Mass Storage devices usb-storage: device found at 6 usb-storage: waiting for device to settle before scanning scsi 3:0:0:0: Direct-Access IC25N030 ATCS04-0 CA3O PQ: 0 ANSI: 0 CCS SCSI device sdb: 58605120 512-byte hdwr sectors (30006 MB) sdb: Write Protect is off sdb: Mode Sense: 00 14 00 00 sdb: assuming drive cache: write through SCSI device sdb: 58605120 512-byte hdwr sectors (30006 MB) sdb: Write Protect is off sdb: Mode Sense: 00 14 00 00 sdb: assuming drive cache: write through sdb: sdb1 sd 3:0:0:0: Attached scsi disk sdb sd 3:0:0:0: Attached scsi generic sg1 type 0 usb-storage: device scan complete I cannot confirm exactly what is happening, however, since even when booted with 'expert' I am not yet given a shell. I should note also that I am not booting from the USB drive; I am booting from diskboot.img through grub (and memdisk from syslinux) or using the kernel and initrd from images/pxeboot. I explored the initrd and the modules.cgz contained therein and confirmed that usb-storage.ko is included. Any other suggestions before I open a Bugzilla ticket? (I have searched Bugzilla too; this is the only related item I have found, but it is woefully lacking in either clarity or responses: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=242322 ) Also, is there an updates.img available? I do not see one on any of the obvious directories on the download servers; according to David Cantrell there should be one: http://www.burdell.org/?cat=11 Wil
