First I downloaded the 14.12 x86_64 graphical ISO and tested it in virtualbox. Everything worked nicely so I decided to give it a go on my base hardware.\r\n\r\nCurrently my system is dual-booting Windows 7 Ultimate x86_64 and Sabayon Linux x86_64 (A deriviative of Gentoo Linux). My intention is to replace Sabayon with NixOS.\r\n\r\nHowever, when booting from either a DVD or USB stick in UEFI mode, the boot process stalls at a random point. The system still responds to CTRL+ALT+DEL but boot proceeds no further and no error significant messages are displayed. Booting from the DVD in BIOS mode works fine however :-/\r\n\r\nI modified the kernel parameters on the USB stick to using loglevel 7 (maximum logging) and tried booting three times in UEFI mode. Each team, the boot stalled at a different stage and no common logging messages where displayed that could indicate why. I used a phone to screencap each time, you can see the results at https://plus.google.com/photos/116682673061080912644/albums/6132475820380017041\r\n\r\nJust to be sure, I also tested the latest ChakraOS live ISO via UEFI USB and it works fine.\r\n\r\nI'd love to be able to give you guys better information on what's going wrong if you can give me some idea as to what information would prove useful."},"comment":{"url":"https://api.github.com/repos/NixOS/nixpkgs/issues/comments/89514404","html_url":"https://github.com/NixOS/nixpkgs/issues/7132#issuecomment-89514404","issue_url":"https://api.github.com/repos/NixOS/nixpkgs/issues/7132","id":89514404,"user":{"login":"OOPMan","id":248980,"avatar_url":"https://avatars.githubusercontent.com/u/248980?v=3","gravatar_id":"","url":"https://api.github.com/users/OOPMan","html_url":"https://github.com/OOPMan","followers_url":"https://api.github.com/users/OOPMan/followers","following_url":"https://api.github.com/users/OOPMan/following{/other_user}","gists_url":"https://api.github.com/users/OOPMan/gists{/gist_id}","starred_url":"https://api.github.com/users/OOPMan/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/OOPMan/subscriptions","organizations_url":"https://api.github.com/users/OOPMan/orgs","repos_url":"https://api.github.com/users/OOPMan/repos","events_url":"https://api.github.com/users/OOPMan/events{/privacy}","received_events_url":"https://api.github.com/users/OOPMan/received_events","type":"User","site_admin":false},"created_at":"2015-04-04T06:59:22Z","updated_at":"2015-04-04T06:59:22Z","body":"The ISO published in the comment you referenced freezes in UEFI mode for me, just as the older ones do."}}
