No, I've never duelbooted anything. Just OC

Larswad low power problem is that then i have 3-10%of battery (i think) u-boot starts(automaticly) then he started, phone not charging, so it means that where is no usb connection(my point) and i can`t reflash it, also then i put in off battery some times, windows or opensuse are reacting that they found usb device but for mi secound just found and not found

p.s. my stupidity was that i leave phone over night without charger with kernel staring then i wake-up it was 0 battery and now then phone have some % it start u-boot

doonit you go to console

Sounds good except I dont know what to do with it

@afteris: Yes, that sounds like it then! So then maybe you need a friend with a N900 and a fully charged battery.
But maybe a suggestion then: Go to one of those retailer stores (bring with you your laptop). Ask them to either borrow a battery or ask if they could charge your battery for a couple of hours in a different n900.
That's not too much to ask, and I think they will help you out.

doonit if you have microsd just load image and start it and you are done

Yes I will try that bit later

@afteris: You mean, use image on SD to boot some os in order to charge batt?
Yes, sounds like a good idea and solution to low batt.

Larswad also i made wires from nokia 6070battery try it have same voltage, becoz i buy phone in usa and in my country where is no offical seller of n900

@afteris, @doonit: Just one thing to try out if you got flat batteries. Try just to load the kernel image to boot from ram (like when having meego on a sd card for tryout):
flasher-3.5 -l -k <kernel>
(same procedure otherwise), see if it boots the kernel that you provide.
Just an idea, maybe you can do the same with the fiasco image, like:

flasher-3.5 -l -k <kernel> -F <image>
