MacFace Posted October 11, 2012 Share Posted October 11, 2012 Hi, EDP is failing on E6520 with ML 10.8.2 consistently with following error message while booting the installer from flash drive. Flashdrive has no read/write issues. Please help me with these errors.

Administrators Bronxteck Posted October 18, 2012 Administrators Share Posted October 18, 2012 seems like a usb stick issue... try a different one if you can. not all usb's are created equal. Link to comment Share on other sites More sharing options...
txtony99 Posted November 18, 2012 Share Posted November 18, 2012 No, this is an issue with EDP and the E6220. I tried every USB port, and multiple USB brands, with multiple bios revisioned E6220's - Get the same as above no matter what. The same media installs just fine on the E6420, although EDP does cause a NO Boot, Blinking cursor on that model as well. Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted November 21, 2012 Administrators Share Posted November 21, 2012 idk but if your doing a bunch of machines i would clone a successful install then modify the extra accordingly until you find a solution. i personally do not have one of those models to help further testing with you. but when i run across issues like that i will just clone a good install. the final object is achieved the same... a fresh OS.
