Unable to boot from my USB Flash Memory Device

Hi there,
I recently purchased a macbook pro with the lion 10.7.2 firmware.
I am experiencing problems with my USB Flash memory as when i plug it in it comes up fine on the desktop and i can browse it. The problem is that when i open up an application such as Adobe Fireworks or Netbeans (Java programming) and try and access files from my USB flash drive, my drive does not appear on the list/menu, it only comes up with my macbook pro documents etc.
I have asked friends with Mac's and they tell me they do not experience this problem. Please can you help me whether it is a problem with my settings or any other issues.
Thank you.

Nope, I dont recieve any massages at all. It just doesnt appear.
Also usually you can drag a file into an application, for example drag an image into photoshop in order to open that image up but this does not work either.

How do I boot from a USB flash drive?

I have two different Toshiba laptops. In the BIOS settings I only see the following options.
Laptop 1:
CD/DVD
FDD
LAN
HDD1/SSD1
Laptop 2:
HDD1/SSD1
HDD2/SSD2
eSATA HDD
CD/DVD
FDD
LAN
Is it possible to make either computer boot from a USB flash drive?
Thanks in advance for any help,
yeto

FDD (Floppy Disk Drive) equates to USB in my Toshiba laptops. Seems like it's taking some BIOS designers a long time to catch up with the rest of the computer world!

Booting from a USB Flash Drive and Optimizing Performance

I know that you can boot Leopard from a USB flash drive, and I have a 16GB flash drive I'm using as a bootup disk on this 2006 MacBook I have that has a broken hard drive (it was recalled, but the recall ended in 2010).
The problem is that it's very slow. I have about 8GB of free space on it, so it can't be the VRAM being too small. The USB speed just stinks. There must be ways to optimize the OS to run off of a slow drive by accessing data as infrequently as possible. What can I do to speed this up? Should I disable hard disk sleeping? Should I use some kind of Mac tuneup/optimization tool's feature?
I plan to get an internal hard drive for it, but I'm stuck with this for a while.

Not all USB2 Flash drives are equal, in fact I bought 2 16 GB USB drives for cheap, as along side of them were even the same brand 16 GB Flash Drives just a different model, for 5 times as much!
Me was thinking how bad could they be? Well, they could be 5 times worse than other USB2 flash drives... LOL on me!
They under extremely rare occasions will Read or Write at 5 MB/s, & very often 1 MB/s...
My Buffalo Flash drives do near USB2's top speed, see some diffs...

Optimizing yours will give little benefit.
You could also do a USB2 RAID0 setup if you have enough ports.

My compaq cq62-214nr will not boot from a usb flash drive

I have a Compaq CQ62-214 NR Notebook. When I enter the bios boot options screen with F9 there is a blank space where Boot from USB/Flash Drive should be. If I enter the bios setup and move usb flash drive up to the first option above Notebook hardrive and Internal CD/DVD Rom ,save the changes to the BIOS then Reboot. Enter the boot options screen again the blank line moves up to the first choice slot but still is blank. If I press enter over that black option the computer does not boot from the OS I have install on the usb flash drive it just starts its normal windows boot screen. YES I have upgraded the BIOS to the lates version F.37
Can somone tell me what is wrong.

Try booting into the one time boot menu.
Step 1: As soon as you turn on the computer on the hp invent screen keep tapping F9 key.
Step 2: you will get boot otions such as hard drive, optical drive, USb drive
Step 3: You can hit enter on the usb flash drive. Should boot from the os on your flash drive

Cannot share a volume from a USB flash memory stick

Hi,
I had a small USB disk drive hanging off my iMac for years. At one point I shared it and was able to access it from other Macs at my house.
Recently the drive began to fail, and since it was a small disk, I decided to replace it with a 128GB flash memory stick instead of a mechanical hard drive. I formatted the memory stick as Mac OS Extended (Journaled), which is the same way the hard drive is formatted, and I copied all my files onto it.
The new volume works fine on my iMac, but I can't share it. In the Settings, if I try to add the drive as a share, nothing shows up. I can share individual folders on the drive, and they appear to be shared, but they are never visible on any of the remote computers. (Everything is running Mountain Lion).
I can't figure out what could be causing this. I checked and repaired the volume several times, it seems fine, it just won't share.
Thanks,
Frank

Aha, a proper Eureka moment.
Thanks for the tip, and it does exactly what I hoped it would.Thank you, I knew it had to be a simple solution ( too simple for me to work out though ! )

Can't boot from a USB flash drive

I believe this ability was lost after updating to BIOS 80.52 following HP's "strong recommendation".No warning was given that this update would remove this ability and see that "Due to security changes, after this BIOS update is installed, previous versions cannot be reinstalled."
I have tried disabling Secure Boot and enabling Legacy Boot, and tried re-applying BIOS defaults.
Is there a particular combination of BIOS settings that I haven't been able to find?As the warranty on my computer expired in July 2014, the HP Customer Support Contact page won't even accept my request for assistance - despite the "strongly recommended" BIOS update being made available *after* this date. I require the ability to boot from USB flash drives ... how can this now be achieved?
Is there an HP BIOS for a more recent HP product with the JasmineR motherboard (or an AMI or other BIOS) available and how could I install it?
Boot a BIOS flashing program from CD or DVD and somehow bypass the HP BIOS's block on updates? Thanks in advance for any advice

Hi, thanks for the quick reply. I don't have another PC handy but will try to find one. The USB flash drive definitely does NOT appear in the boot menu - even as an HDD or CD/DVD as I have seen mentioned elsewhere as a possibility - and all USB devices are enabled in the BIOS settings and USB HDD and USB Floppy/CD are above rEFInd and all other entries in the boot order. I should also have mentioned that I've tried a (Lexar) USB flash drive prepared approximately a year ago with GParted Live which *has* previously booted the machine, and also different models of flash drives (Toshiba, Transcend) and different methods of preparing them such as burning bootable ISO images with Win32DiskImager, Universal USB Installer and Rufus, and manually creating and formatting a bootable FAT32 partition with diskpart (as per https://technet.microsoft.com/en-us/library/jj200124.aspx) and copying in System Rescue CD/GParted/Clonezilla files, ensuring there is an /EFI/BOOT/BOOTX64.efi file. In diskpart, the "attributes disk" command shows that the USB drives are not marked as bootable and "help attributes disk" says READONLY is currently the only disk flag that may be changed. (Don't know if this means anything as the GParted disk isn't "bootable" but did boot) Did the BIOS update disable enumerating USB devices until later in the Windows 8.1 boot process?

Run XP / Vista from a USB flash memory on my Macbook Air

Hello!
Does anyone know if it is possible to boot and run XP directly from a USB stick?
I am fairly new to Mac. So far I like it a lot however, due to my job I need to run some things in XP or Vista. Instead of "polluting" my new Macbook Air with a partition with XP I thought it would be neat to run XP from a USB stick. They are cheap and quite large nowadays but I really have no clue if it is doable technically. It might be too slow or there might be other issues that I don't know of.
Can anyone shed some light or point in the right direction.
All help will be highly appreciated.

I would guess that performance wouldn't be so good trying to run XP from an external hard drive, but I haven't tried it nor do I know if it is possible. I'm in the same boat with needing to run some XP programs.
I've been using VMware Fusion and it works well. However, the MBA runs hot and battery life suffers when just running VMware without much going on in the XP machine. You can probably put the XP VM on a usb key and have VMware run it from there. As for the software running in a VM rather than native, the programs run and the speed is tolerable but I don't mistake it for my ThinkPad. Depending on how much resources your software needs, the MBA may not be a good fit.

Booting from a USB Flash Drive

Is this possible? I travel a lot and to have a flash drive for use in an emergency would be great.

This could be the device you are looking for, the TechTool Protege. It says it is a 1 GB, flash memory, pocket-sized device that can boot Macs via FireWire. It says it comes with the latest version of OS X already on it. It sounds interesting, but I've not heard of it before.

Edit: This seems to be the same device without the TechTool stuff on it.

Booting a DMG from a USB Flash Drive?

Is there anyway I can boot from a USB flash drive? I don't have a DVD burner to burn the image onto, so I have to resort to this. I'm running an Intel iMac (late 2006) on Tiger.
Any help is appreciated.

If you mean boot up your Mac then the answer is no. If you mean open a .dmg file then the answer is yes.

Booting from USB Flash Memory Card Reader on RS480M2-IL (Test Results)

I just completed testing my USB Flash Memory Card Reader (see profile) as a boot device and wanted to provide feedback to the Forum.
A UBS Flash card will show-up on the Advanced Bios Features menu, Hard Disk Boot Priority list, when a Flash card is physically present in a card slot. It showed as "USB-HDD0 : AFT PRO -8MX CF 0" with a 256MB Compact Flash (CF) card for my test. Using the enter key on the Hard Disk Boot Priority list allows for ordering priority, which was necessary to place the CF Drive before my real Hard Drive for the card to boot. When the card is removed, it drops from the list.
I initialized my CF card as a DOS system disk using HP's USB Disk Storage Format Tool v2.0.6 for the test.
Since it is recognized as a Hard Drive, it boots as the C: drive, not A/B Floppy alternative.
I also ran a quick test to see if XP Pro Setup would see the drive. It does show as my D: drive partitioned FAT. Too small (256MB) obviously for XP Pro install, but it does present opportunity for larger size flash modules. My Flash Reader actually has 4 different disk functions/slot groups, so XP Setup acknowledge the presents of those empty three slot groups as "Unknown Disk" on the drive list.
I hope the information is useful for anyone planning a build or looking for alternative boot methodolgy with the board.
This board just gets better and better.

So with a nice size flash memory u could start your box with a key drive and lock up your computer when you leave it unattended.

Bootcamp woes, unable to boot from USB and DVD drive reads all DVDs blank

My partner and I are completely unable to install Windows using Bootcamp. We have tried dozens of solutions on the internet.
2011 iMac (purchased in by me and my partner 2012) reads all DVDs as blank. We have (hilariously) another Mac, an MBP, that has the same exact problem. You'd almost think "Superdrives" eventually just stop working or something. So obviously we can't install Bootcamp on the iMac using a DVD.
But what about a USB stick? Well after modifying the plist file and writing a bootable Windows USB and trying to boot from that, we were greeted with the mysterious and apparently yet-unsolved "no bootable device" error.
So our iMac can't boot from USB drives or read DVDs. We've only owned it for two years. And this is the second Mac we've owned where the Superdrive has died. And we don't even use DVDs more than like once a year.
But anyway, can someone tell me what we're supposed to do if we want to install Windows aside from throwing money away to buy another Superdrive that is probably going to die again in a year? Maybe a way to make our mac boot from our USB stick? Something?
Thanks.

Should you have another drive with a MBR, use it to rule that issue out. Alternatively create a GPT on the flash drive and try to boot from it.
What options are there for the usb controller/boot priorities/order/options? Does the laptop recognize the usb flash when already in bios setup? Should there be any form of choosing the device to boot, use that with the flash drive in the socket, then switch it with the external drive.

[SOLVED] can't boot from ssd after "reset" from recovery usb flash drive

I have a Twist s230u with the original Hitachi 500GB hdd, running Windows 8.1. I want to replace the Hitachi 500GB hdd in my Twist s230u with a PNY 240GB SSD that i've purchased.
While running Windows from the Hitachi HDD drive I followed the "create a recovery drive" procedure to create a recovery usb. Then I removed the Hitachi HDD from the s230u and installed the PNY 240 SSD in its place. I booted the s230u from the recovery flash drive that I made. I selected the "Reset Your PC" option and then the option to wipe all partition/files. After the Reset completes, I try booting from the SSD but am unable to do so. I just go back to the F12 boot menu.
I put the SSD in a drive dock attached to another computer. Disk Management shows the partitions as follows -
I've looked at the partitions on the SSD after the Reset - Disk Management console shows a 1000 MB Recovery partition, a 260MB EFI System partition, and a 221GB primary partition with volume label Windows8_OS. It is not marked as Boot, Page File, or Crash Dump.
Diskpart shows an an additional 128MB Reserved partition between the EFI partition and the primary partition.
I do notice that the 10.6 Lenovo Recovery partition is not present - but I did make sure that I included that partition on the recovery key - though the files on the recovery key only use 8.03 GB for some reason. Made the key on two different flash media.
Diskpart also shows the following for the SSD:
DISKPART> attributes disk
Current Read-only State : No
Read-only : No
Boot Disk : No
Pagefile Disk : No
Hibernation File Disk : No
Crashdump Disk : No
Clustered Disk : No
(It also looks like this when I run DISKPART from the recovery media with the SSD inside the internal drive bay of the s230u.)
When I did the Reset on the SSD in the s230u, and when I tried to boot from it - I had the Secure Boot disabled, the "Legacy Boot first" option set, etc.
Can anyone point me in the right direction to be able to boot Windows 8.1 from this SSD in the s230u? I've been working on this for a couple of days.
(I also tried cloning the HDD to the SDD using Minitool Partition Wizard, Macrium Reflect, Clonezilla, Acronis, etc - the SSD wouldn't boot after those clone operations either, and I thought maybe I'd have better luck with a reinstall from the USB recovery media.
(I also tried installing from a Windows 8 iso I burned to a DVD. I got a product id mismatch message when I tried to install from that, and I was not allowed to proceed.)

well, I seem to have solved my own problem. Maybe someone will learn from my mistakes.
I went into System Setup, went to the Startup tab, and changed the boot setting from "Both" to "UEFI Only". After doing this I booted from my USB recovery drive, and Reset the PC. After the Reset, I booted the s230u from the ssd, and I booted into a fresh Windows 8 installation.
It seems that the Reset operation could not work properly while the boot setting was "Both" (UEFI and Legacy) and "Legacy First."
I got a clue when I looked at the contents of the EFI System Partition and there was nothing there except a Temp folder. The EFI System Partition had not been properly written by the Reset operation. I got some helpful hints on how to see the contents of the EFI System Partition here - http://www.fixedbyvonnie.com/2013/12/how-to-repair-the-efi-bootloader-in-windows-8/#.U-Qz2_ldW7q
I've also buggered up my original HDD now, so that it won't boot to Windows now. Now to fix that!

I've bought a new USB flash memory. I plugged it in the USB port then a message come out: Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled.... Please help...

I don't know what to do. I plugged that USB in both ports but the same message came out. I charged my laptop and the same thing happened again. The surprising thing is that I tried plugging the USB in my cousins laptop (Macbook Pro) and it worked!!! but not with mine. The USB flash memory made by PNY. Please help...

There are two types of USB 2 devices - low power which consume 100 milliamperes or less from the USB bus and high power which consume up to 500 milliamperes. Your flash drive is probably a high power device and is overloading the USB bus of your computer. (Some notebooks can support only low power USB devices.)
I know that my MBP's USB ports support high power devices but I've come across reports that not all high power devices will work on the MBA and that might be the case for your flash drive. My guess is it has a large capacity? 32GB or more?

Toshiba 40SL733g - How to play video files from USB flash memory

When I plug my USB flash memory in USB port, Media Player menu shows up with two options : Photos and Settings.
How do I make my TV recognize and play video files from USB flash memory?
Flash is on FAT32.
I have tried to play avi, mp4 and mkv files but nothing happens. It looks like flash is empty.
Could you please help me solve this problem.
Thanks!

bzunic, have you updated the firmware for your model?.
With my own set, (32RL900A), the instruction manual said that certain buttons on the remote control were "unused", however, after the first firmware update, the previously "unused" buttons were used, (In our case, Time Shift, Record, and so on).
The reason I talk about this is, these features became available after a firmware upgrade, and were not mentioned in the user manual, in our case, and a later download of the instruction manual for our model actually gave the instructions for the use of these features, which were shown as "not available", in the original instruction manual supplied with the TV, but became available after the firmware upgrade.
Let us know how it all works out ............

Install arch voodoo from usb flash memory

I am interested in anybody crazy enough to try this tutorial I made http://wiki.archlinux.org/index.php/Ins … ash_memory , I tested it with my hardaware and until now it was worked out great, but i am looking for second opinions.
I also posted an updater script that will update the install packages, so you can always carry a freshly updated arch install, anybody willing to test it on any spare usb flash memory or external hd they might have, please do so.
Cheers!
