GTX Gaming — Install OS over the network

No USB stick, no site visit. Mount an ISO from here as virtual media on the machine’s BMC or NanoKVM, power on, install.

Route A is the one to use. It needs no DHCP, no chainloading and no network before boot — the machine boots from the mounted ISO and you set the static IP in the installer, same as you would from a USB stick.

Route A — mount the OS installer directly (recommended)

HardwareHow to mount
BMC / IPMIVirtual Media → mount ISO by URL (or upload) → set boot device to CD/DVD → power on
NanoKVMImages → upload or select the ISO → mount as virtual USB CD-ROM → power on

Network during install: the GTX server LAN has no DHCP, so the installer will fail to autoconfigure. That is expected — choose manual/static configuration and enter the machine’s own public IP, mask, gateway and DNS. Ubuntu and Debian both offer this on their network screen.

Route B — iPXE boot menu (one small ISO for every OS)

Mount the 2.4 MB netboot.xyz.iso instead of a full installer. Useful for rescue tools and OSes not listed above, at the cost of typing network details at the console first.

It will report a DHCP failure — expected. Press Ctrl-B for the iPXE shell:

set net0/ip 89.34.97.10
set net0/netmask 255.255.255.224
set net0/gateway 89.34.97.1
set net0/dns 1.1.1.1
ifopen net0
chain https://boot.gtx.gg/boot.ipxe

Substitute that machine’s address. The GTX menu then loads and passes the same static settings through to the installer.

Unattended installs

Optional. Point the installer at these to skip the questions (disk layout still manual):

Debianhttps://boot.gtx.gg/cfg/b65faec73d7bb0b44a27d078f895ef29/debian/preseed.cfg

Windows needs nothing extra — Win2025-unattend.iso already carries its autounattend.xml.

These config URLs contain credentials. The random path segment is all that protects them — treat it like a password. Rotate by renaming the cfg/ folder.
Unmount the ISO when Setup finishes, especially for Windows — it boots with no keypress prompt, so the machine will loop back into Setup.
