These are the single-boot options available to you:
Standard for HD
Standard for RGB
Virtual C + Eeprom
Virtual C + Eeprom for HD
Virtual C + Eeprom for RGB
You’ll notice that you have new options compared to the One-Click Install System. Installing the Softmod for HD (High Definition) means that your Softmod will be set so your Xbox is best displayed with a High Definition TV.
You only get the options to install EvolutionX or UnleashX in this section, but you can easily go back to the Install Dashboards section and change it (to XBMC for example).
The USB Version will give you the added option of Xbox Media Center, plus it will install the following applications to your Xbox (at location E:\Apps)
Enigmah NTSC-PAL Video Patcher
DVD-X (Region Free DVD Player)
One small rule, when installing a Softmod with Virtual C, don’t select a Softmod Dashboard, because the Softmod tricks your Xbox into thinking that the C Drive is still stock (unmodded), so in order to access the MS Dash properly you need to remember this.
Dual Boot Softmods
Unlike the Single-Boot Softmod, the Dual-Boot offers much more flexibility.
The two options you have are:
Hacked Dash / Softmod Menu
Hacked Dash / MS Dash
You firstly have the option on how you want to control your Dual Boot. After selecting this, you will proceed to the same options as the Single Boot.
Please note when you use the Hacked Dash / Softmod Menu option, when you boot your Xbox in this state, any Virtual C Drive is turned OFF leaving it exposed. You may not want to use this option if there’s a possibility that your Xbox can be used by someone that could easily format it on you.
The Hacked Dash / MS Dash option allows you to use Xbox Live properly (only with Original Games though). For this to work correctly, you must have you Xbox unmodded to set up your Xbox Live Account. Once this is done, you can proceed to apply the Softmod to your Xbox.
