Help! Phone won't boot!

[Roooooo]

I have a Desire for 2 days now. I came from the gym and all of sudden my phone was turned off.
I thought maybe battery low so i put it in the charger in turned on.

But my phone wil not boot! I come into Hboot menu that says:

Bravo pvt1..... etc etc and 4 options:

- fastboot
- recovery
- clear storage
- simlock


I cannot get past this screen! I tried everything I could think off. Power off, waiting, removing sd card, pressing al kinds of buttons but I am stuck now!

Please help!

When I press the powerr button it says something like: SD card checking...... and then It goes back to the main HBoot menu with this options:

- Bootloader
- Reboot
- Reboot bootloader
- Power down

Wow i finally got passed the HBoot. I had the battery out for 15 minutes.
BUT: It now says: Safe Mode. And now phone switched off again by itself.
