Hi, I’m new to umbrel OS, first time installing it but I keep getting “Unable to compute new partition table Insufficient space can not add partition 6” What am I doing wrong? Thanks, ---

hey, that error suggests umbrelOS can’t fit the partitions it needs onto the drive it’s trying to use, but it’s hard to tell why without a bit more info. What are you installing on: a Raspberry Pi, a PC, or a VM? Also, how big is the drive you’re installing to, and which umbrelOS image did you download? If you’re using a USB stick for the installer, include its size separately from the destination drive. A photo of the full error screen would help too. I’d hold off on deleting or resizing any partitions until it’s clear which drive it’s complaining about. ---

Hi, I’m installing it on a mini PC > Specs Intel Celeron 3865U 1.8GHz 2 Cores, 4GB RAM, 128GB SSD. Will unbrel OS work on that specs? I tried 2.0 beta and 1.7.4 both same error. I’m using USB stick and use balena to create the USB stick installer. The SSD is clean no partition. Thank you. > > ![20260918_213018](https://canada1.discourse-cdn.com/flex030/uploads/getumbrel/original/2X/b/ba6dfb4f9e28ccd933a51fea7d15ceef5341b6e2.jpeg) ---

Same problem. Booting from 16Gb USB Drive (I tried two different USB drives), on baremetal PC ---

The problem was the 16Gb Pendrive. No issue using a 32Gb pendrive ---

You’re correct it requires at least 32gb USB drive. And it’s on umbrel website. ![Screenshot_20260922_224931_Chrome](https://canada1.discourse-cdn.com/flex030/uploads/getumbrel/original/2X/5/5084c12b791902e253bbcf830027ae834696dd6c.jpeg) ---

And to install umbrel OS on internal storage device the image to download should be Onboard storage or an internal drive. ![Screenshot_20260923_003308_Chrome](https://canada1.discourse-cdn.com/flex030/uploads/getumbrel/original/2X/6/66ed7df86c046242e5723267a3b1d30f4b378daa.jpeg)
