So I keep getting prompts to install the update which fails after going to the gears menu and finding only 200Mb is left in Partition .... any way to opt out of the update and just Revert back ........
To install windows 10 you need to have 300-500 mb space in sys partition....I think you missed that criteria so no problem..What you have to do now is revert to windows phone 8.1 via WSRT or LSRT and then install the windows insider and check the about status..
If it has >300mb then goahead to install windows 10 ....This time your installation will be successful :)
Note : Do this if u want to install Windows 10 TP despite risk and if don't want to use Preview for Developers to get 8.1 update and stay on it for a while until MS supports other models
