Hi, I'm trying to install debian-6.0.5-amd64-CD-1.iso from USB memory-stick. The problem is, that Debian-Installer is not able to "Detect and mount CD-ROM" during the installation process. The USB memory-stick is a 2GB model containing MBR and FAT32 file system: # fdisk -lu /dev/sdb Disk /dev/sdb: 2013 MB, 2013265920 bytes 62 heads, 62 sectors/track, 1022 cylinders, total 3932160 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x4a02df63 Device Boot Start End Blocks Id System /dev/sdb1 * 62 3928567 1964253 b W95 FAT32 # file -s /dev/sdb1 /dev/sdb1: x86 boot sector, code offset 0x58, OEM-ID "SYSLINUX", sectors/cluster 8, Media descriptor 0xf8, heads 62, sectors 3928506 (volumes > 32 MB) , FAT (32 bit), sectors/FAT 3832, serial number 0x4373da42, label: "debian64 " # MBR has code needed for booting(first 440 bytes) and syslinux(4.05) is installed to mentioned partition. Syslinux configuration(syslinux.cfg) is very simple: # cat syslinux.cfg DEFAULT vmlinuz APPEND initrd=initrd.gz iso-scan/filename=/debian-6.0.5-amd64-CD-1.iso # Debian-Installer starts successfully and I'm able to specify locales and keyboard layout, but "Detect and mount CD-ROM" fails. If I start the ash("Execute a shell" option in Debian-Installer menu) and mount memory-stick FAT32 partition to /cdrom using BusyBox mount utility, I'm able to pass the "Detect and mount CD-ROM" step, but then I'm stuck in "Load installer components from CD". I even copied entire content of the debian-6.0.5-amd64-CD-1.iso image to a directory in memory-stick and then mounted this directory using the Debian-Installer shell, but this didn't help either to pass the "Load installer components from CD" step. Any ideas how to proceed here? Am I doing something wrong? regards, Martin

If I startSounds like you've successfully installed SYSLINUX to your UFD and it's up to entries in the Syslinux configuration file and layouts outside of SYSLINUX.> the ash("Execute a shell" option in Debian-Installer menu) and mount > memory-stick FAT32 partition to /cdrom using BusyBox mount utility,I would have mounted the UFD to another directory then done a loop-mount of the ISO.> I'm able to pass the "Detect and mount CD-ROM" step, but then I'm > stuck in "Load installer components from CD".

Am I doing something wrong?Have you considered the Net Installer? There's two, one around 180MB, another around 50 MB.> regards, > Martin-- -Gene

[syslinux] unable to install Debian using syslinux 4.05
Hi Martin, although this is not a syslinux issue, I'll answer on-the-list (moderators can advice on feasibility of continuing this discussion here).

As far as I know that won't work, you need to copy some files from within the CD-ROM and place them on the USB disk.
