- install usb stick
@niuk: I had problems with that too. Try different USB Sticks and different methods to write the ISO to the USB stick.
If all else fails burn a CD or an external HDD wich emulates a ODD drive - I took the last route because I regulary need this and would not trade it in again

Hi,
"formatted on Linux" makes no sense, because you overwrite any formatting with dd!
Do you use the same USB-port on the server? Perhaps the bios don't support all ports for booting?!
Udo
right,
and with dd all formating before is lost! - this is the reason, why it's make no sense.

Hello. I would like to install Proxmox 4.4 from USB. I use Linux Mint 18.1 and i formatted the pendrive to fat32 and i used dd, but i have got still the grub rescue shell......
Hi,
do you sync after dd and write long enough before disconnected the usb-stick? (the sync must be finished)
And again - it's helpless to format the usb-stick before write an iso with dd onto the disk. the dd overwrite an excisting format!
Udo
Hi,
this is correct, but you must do an "sync" after that and wait with disconnect the stick until the sync is finished. Otherwise it's can happen that not all data is written to the usb-stick.

Hi,
2 sec. are much to less. Has your downloaded iso the right size?
you can use this methods:
Code:
dd if=proxmox-ve_*.iso of=/dev/XYZ bs=1M; sync
dd if=proxmox-ve_*.iso of=/dev/XYZ bs=1M conv=fdatasync
Code:
ls -l Downloads/proxmox-ve_4.4-eb2d6f1e-2.iso | awk '{print $5/(1024^2*5)}'
104.359Hi,
the same size of the iso don't say, that the iso is correct - for this you should compare the hash.
Code:
md5sum Downloads/proxmox-ve_4.4-eb2d6f1e-2.iso
e453b3e1038d8b95f4a6d12cb233c389 Downloads/proxmox-ve_4.4-eb2d6f1e-2.isoBut perhaps you must change something in your bios to boot from the USB-Stick - like bios/efi-boot, boot order, type of usb-handling?

What kind of hardware do you have? I had problems with older servers and in general older motherboards using usb boot. In those cases, I use a usb dvd drive and a dvdrw disk to avoid hours of fruitless struggle. This method always worked.
In any case, double-check you're not booting off anything but the usb drive.
