Инсталиране на Ubuntu server на usb flash памет

[...]

Здравейте. Използва ли някой Ubuntu server който е инсталиран на флашка, а не на механичен твърд диск или ssd. Какъв софтуер се използва за инсталацията под windows (rufus, live-usb, unetbooting). 16gb флашка достатъчна ли е. Трябва ли да се дели флашката на дялове за да може промените след ъпдейт на ubuntu да се запишат на флашката. Възможна ли е инсталация по стандартния метод със cd на убунту и указване на флашката, като външен твърд диск. Целта е след рестарт на компютъра да имам възможност да избирам кое да ми се стартира уиндоус или линукс. Не пишете за виртуален сървър използвам такъв. Ще се използва версия Ubuntu server 17.10 x64

Точно за убунту си има всичко в техния форум

                                    There are several alternatives, that might work well for this purpose.
  Persistent live drive

  You can install a persistent live system with a 'casper-rw'  partition, where you store the custom data (installed program packages,  special files and tweaks). This can be done from an Ubuntu family iso  file, when you use the tool mkusb as described in the answer by C.S.Cameron.
  You might find it convenient to start from a compressed image file,  that is already made to fit an 8 GB USB stick or memory card. See the  following link,
  Compressed image file with a persistent live system
  and scroll down to see all the information about the available systems.
  The images expand to 7.8 GB because some USB sticks are undersized (slightly smaller than then nominal size).
  Installed system

  You can create an installed system in a USB stick pretty much as you  install a system into an internal drive, but there are a few things,  that you should consider in order to succeed.
  When the basic system is installed, you can boot into it, make it up  to date and add the custom data (install program packages, special files  and tweaks).
  You can use the following link and links from it to create such a system from 'scratch',
  Install an Ubuntu system to a USB stick
  Please notice that 8 GB is not enough for an installed system with  standard Ubuntu, but works well with Ubuntu family flavours using light  desktop environments and light application programs,
 

• Lubuntu with the ultra light LXDE
• Xubuntu with the medium light XFCE

 You can take a short-cut and clone a mini system, that is already  created, and that can boot both in UEFI and BIOS mode. Clone from a  compressed image file to the USB stick. The images expand to 7.8 GB  because some USB sticks are undersized (slightly smaller than then  nominal size). See the following links and links from them,
 

• A portable installed system, that boots both in UEFI and BIOS mode
  
• help.ubuntu.com/community/Installation/UEFI-and-BIOS
  

dd_dus-lxde_16.04-UEFI-n-BIOS_2016-05-07_intel-4-pendrive-7.8GB.img.xz contains a light-weight desktop version with mkusb-dus.
  A system likely to work in all the computers of the participants

  Please consider the various computers of the participants of the  event: UEFI mode and/or BIOS mode; 64-bit and/or 32-bit processors,  various graphics chips and wifi chips, new and middle-aged (and maybe  old) computers.
 

• A persistent live system is more portable between computers.
  
• An installed system can be updated and modified completely and is more stable. But you should avoid proprietary drivers, if you want portability.
