• That's the so-called recovery-menu. You can find out a little more via our recovery-mode tag-wiki (especially it also lists some custom-recoveries and their tags here). Via that page you can also check out other related questions. – Izzy Oct 30 '14 at 12:31

• Clockworkmod and TWRP recoveries are great; although I'm not sure if they are available for your phone, you will have to search for it. However, if you only want to remove Google apps, you can do it by rooting the phone and removing the corresponding .apk files from /system/app. This is dangerous! You can brick your phone if you remove wrong files! Do NOT do this if you aren't totally absolutely sure about what you're doing or you have an original ROM you can restore! also, I think you can click 'disable' in Settings/Apps if your Android version is recent enough, that is much safer. – matega Oct 28 '14 at 15:59
