How do you get in windows safe mode?

[OptoMan]

Windows Safe mode, Windows 10 is a bit different than previous versions of windows.  First options, if you can actually get to and log in to your desktop, go to settings > update and security > recovery > advanced startup, restart now.  This gives your advanced boot options including recovery, restore points (which you’re probably not using and shouldn’t anyways), command prompt, and such.

Second option with Windows 10 is to have a 10 startup disk — 10 install media for instance put on a thumb drive.  you *could* make one with your tablet, but the best thing to do is to hop on a computer and get the Microsoft Windows 10 media downloader/installer to grab the iso.  It’ll make the thumb drive for you I think, or you can save the iso and make the drive yourself.

Thanks for the tip, i wil try with a startup disk.

sure .. safe mode for the most part boots a ‘working’ [mostly] system all the way to the desk top, but with minimal drivers and services running especially non-microsoft stuff, app autostarts too.  so, it’s not your typical desktop you want to use all the time .. seems you’re heading that way cause you can’t boot normally (where you could get to safe mode by a couple different software settings followed by a boot) .. so a thumb drive is the normal way to do that.

almost typed way too much on here — they don’t have a hotkey at boot anymore for safemode — if left plugged in to usb power, windows should repair itself at boot, noticing failed startups, even if it takes a while.  windows install media will offer to repair if it finds installed windows.  no reason those two shouldn’t work.

I have made a bootable win10 usb, i change the startup mode in the bios in my usb drive, but it is not booting from my usb, did i miss something?

I want to boot up in safe mode to do some repairs, peace of cake with earlyer win versions, but with win10 its not an easy thing to do.

Thanks

sorry, been several days didn’t get a reply notification — I’m the kinda guy that will go around looking for trouble!  I’ll double check and confirm in a few minutes — it should be a gpt formatted usb drive (diskpart, select proper disk, clean, convert gpt, create partition primary, format fs=ntfs label=whateverhere quick, assign letter=ilikeg .. and xcopy /e /h all of file-manager-mounted windows iso to the new usb drive), and then with that OTG’d to the tablet, with BIOS’s OS Image ID set to Windows 10, a straight up normal boot should boot off it ..

be back in a while, battery is charging on tablet .. I do however remember it being really easy to boot a real windows boot disk quite easily!

before I forget, do not forget that if you can at all login and reach your desktop (turn the radios off quick to reduce resource use and any pending stuff that we know won’t finish or let you finish!), you can go to windows 10 settings, last main submenu “update and security”, then fourth option “recovery” .. then “advanced startup” with it’s only option there to restart — there’ll be a funny reboot and an option menu that is so akin to old F4 menus of past: *safe mode*, restore point, restore from some [giant] image [you never made], *repair* — cool stuff.

the windows bootable udisk will start the windows installer, which does have options to repair computer, a terminal and a few others I’m sure

Ill check if its formatted in ntfc, thanks.

iff you have a copy of the files default, sam, security, software and system for me, located in C:/windows/system32/config  from your iwork air, i think i can repair my windows 10.

hey you’re right there, hello — I saw that post but not the person on it — make that good installable udisk, and hit repair computer — it’ll do a ‘repair install’ —

just so you know, it’s not really a good (practical) idea to use someone else’s registry.  if it was a backup of yours, maybe you’ll see it load a similar but ancient version of your familiar device =)  the protocol here is to do a repair install — you are looking to loose a lot of important configuration information though, information about users, and installed softwares .. which means you’ll have to reinstall most software and set your settings again.  you’re data should still be somewhere however, and that’s really the only thing making it a detour to instead just reinstall windows.

btw, it’s the gpt partition table on the udisk that’s really important, I would continue to use NTFS tho.  I have installed windows 10 from FAT fs formatted usb drives — the misnomer we might catch here is the firmware installer from Cube says requires ntfs udisk .. it’s the same but it’s not .. so cool

okay — here’s what’s confirmed, and you will need a keyboard or _maybe_ just a mouse — tell me how you got to the x: prompt without a keyboard and we might figure something out..

usb gpt ntfs as windows 10 install media — OTGd with some charge of course, hold vol-up when you power on, and from bios check in Advanced > System Component, that OS Image ID is “Windows 10” — then tap the E on exit in lower right legend a time or two to get to main first bios menu again, and then navigate all the way over to the Exit tab .. on the bottom you should see your thumb drive listed, when you select it, it goes

I can’t see past the language chooser right now .. but it’s the windows 10 installer from MS and there’ll be an option to repair your computer.  =)  be over here .. best of luck and you’re not far off

you’r underline-shortcuts use the alt modifier key, or you can alternatively navigate from available options with tab and shift+tab to rotate backwards .. enter will open or activate, if it’s a checkbox, using spacebar is good.

holding power for about 8 seconds kills the power — it’s above operating system to respond to that.  about 4 seconds on typcial pc’s

I have a ntfs windows 10 boot usb, but when i select my usb it will boot into the windows boot menu from the iwork8, look like it is somehow blocked.

I checked the usb on my normal pc and it is working fine.

well — if you really selected the usb from bios, the bios will scan the usb to see if it can boot and if it can’t it’ll fall back on standard boot. so that means any usb thumb drive will appear in bios, which you can then at least try to boot from .. so this means that the usb drive is actually not bootable from your tablet ..

these tablets are actually uefi not bios.. unified extensible firmware interface .. it’s a giant extension from bios that does all the bios stuff and more. bios is a good way to refer to the options and menus and stuff you can adjust before you start to load an operating system. the things that make it UEFI that matter here, and especially to us and our cube firmware being android and windows 10 and our two choice boot menu of course, are that UEFI recognizes not only the older style of partition table, mbr (master boot record) that has some limitations that do affect us, but also a newer style called GPT (guid partition table, guid being globally-unique identifier) layout as well.

uefi specification actually has provisions to boot from MBR disks. but bios or uefi, MBR boot drives have to be specially prepared with something called a boot sector that helps find your target operating systems or at least a choice of operating systems. GPT doesn’t use boot sectors and it’s actually easier to make bootable drives because of this.

yes, uefi has compatibility support to boot from mbr style boot disks, that doesn’t mean cube opted to utilize that support.
so my real question has come to what you used to create your bootable usb drive — here’s why — if you used the ms provided windows install media creator to download the image for you, that’s right. but it seems the tool creates MBR style udisks.
further, but not mattering to us for this, what style you boot into windows installer is what style will be installed on the destination machine if that machine doesn’t have a preexisting boot setup —

I’m wondering if your PC is booting just fine from an mbr boot disk ..

I made a thread with a walkthrough flashing iwork8 ult dual boot files and it shows how to create udisks for each android and windows 10 _from cube_ ..

but you need a ms provided installer on udisk which is handy to have .. I’ll post something in a few minutes

[OptoMan]

windows 10 media creation tool — navigate almost carefull so you aren’t
making a drive but saving the iso file for later — 64 bit english, home,
uhh if they ask

know where the downloaded .iso file is. file manager on your windows
machine, find the iso file and right click, and select mount. you should
now see a new drive on your system in your left pane — that’s everything
the iso image file contained .. ready to burn bit for bit to an optical
disc

dos prompt. tap windows key on keyboad and start search for ‘cmd’ you’ll
see the program, but instead of running it yet, right click it — run as
administrator and confirm
type and run ‘diskpart‘

in here we’ve got some neat stuff —

list volume #you’ll see the mounted image file, remember this, pretending
#here, F(from), and probably you usb drive as long as it’s
#not blank, say T (to)
list disk #match the capacity of your usb disk to see what disk number
#it is.. if it has a recognizable filesystem, it’s considered
#a volume and the same driveletter, T
select disk <n> #T’s number if it’s ya — coulda skipped listing disk
and #selected volume but I think anyone who’s anyone’s usb
#drive has a thrashed partition table or a nonwindows
#filesystem, so no volume letter.
clean #partition table is blank but it is mbr
convert gpt #so important .. pretty sure cube tab only likes uefi mode
#boot .. this will boot uefi mode only on any computer along with the cube, we’re not
#doing a boot sector
create partition primary
format fs=ntfs label=”win10inst” quick #if an aged, aged drive, no
#quick, it would actually write and then read to every block on the drive takes many minutes per GB this tests each bit and will tell filesystem to not ever use bad ones whole nother story life span of flashdrives is thousands and thousands of operations.. ctrl+c will cancel such operation, but your drive is mounted and yet stupified so you’d pull out the udisk, place in again and start over maybe with claimed drive letters you now can’t use.  pick a good name too
#like sparky

assign letter=T #if format didn’t give it one and if T doesn’t work, try
#U.
exit #this is not a trick

back to command prompt — remember your usb’s new drive letter and your
mounted image drive letter ..

xcopy /e /h f: t: #copies directory trees, flag e does everything as
#in even empty folders and /h includes files that
#are hidden and/or system flagged themselves

this will take a good 10 minutes

exit #escapes command prompt

there ya go

better tell you the story, erase the file system, there went all knowledge of bad blocks .. again?  wear leveling is part of flash technology .. I have had one usb drive start giving me errors a few years ago

[OptoMan]

pretty sure that’s what’s going on .. give it a whirl.  all the many many posts everywhere about making boot disks .. windows disks are easy.  linux and specialty dos disks aren’t — which means then you’d need a deceptively complex and overtly misguided drive creator’s assistance

don’t call me names yet just you see
