Cant detect any boot disk

Hi,
I booted my Macbook pro the other day and all i got was a folder with a question mark. I read few forums and tried a few options.. Nothing worked every time I tried to recover the macbook would re-boot and come back to the question mark folder.
I eventually conceded that the hard drive was toast. I replaced the hard drive but still have the same problem. The strange thing is that when I boot from a recovery USB, Disk util can see the new drive, it can verify the new drive.... nothing seems to be wrong... But, when I go to the Apple Logo -> Startup Disk, Startup Disk can not find any available disks!!! How is it that Disk utility has no problem finding and verifying the disk but it will not show up in "Startup Disk"???
Any help much appreciated.
Thanks

HI there CraigRKL,
If this was a new hard drive, it likely doesn't have an operating system on it. You will need to boot to the Recovery HD, format your new hard drive, and install OS X. The steps in the article below has the steps you need to follow.

IPhone 3G cant detect any WiFi since updated to 3.0 OS

Hi, my iPhone 3G cant detect any wifi. Reset Network - DONE, Restore Firmware - DONE. Its happen since I updated my firmware to 3.0. Please do guide me. Thanks. Rgds from Malaysia.

It took me days to find it...
So, let's go:
My iPhone does not connect to any WLAN/WIFI networks at all - just some days after updating it to 3.0. Now what to do?
1. Change your WLAN-/WIFI-station to non secured (no password)
2. Try to connect your iPhone - most probably it won't connect
3. Change airplane mode to "On" and wait 10 sec
4. Change airplane mode to "Off" and wait 10 sec
5. Change airplane mode to "On" and wait 10 sec
6. Change WIFI to "Off" and wait 10 sec
7. Change WIFI to "On" and wait 10 sec
8. Try to connect - most probably it will connect!
9. Now change your WLAN-/WIFI-station to secured 128-Bit-WEP and give it a password
10. Change WIFI to "Off" and wait 10 sec
7. Change WIFI to "On" and wait 10 sec
8. Try to connect with your new password - most probably it will connect again!
In my case it now even connects easily to all the other networks again now!

No boot disk detected or boot disk failed

I'm asking this for my father. He does not have the internet right now. Nothing to do with this issue though.
He has a Pavillion 23, model # 23-1270. A week ago he went to turn on his computer and got an error message saying, " No boot disk detected or boot disk failed. My sister called HP and one of the techs said it was the hard drive and it needed to be replaced. So it was replaced. Went to put Windows 8 back on from the disk, and it still pops up with "No boot disk detected or boot disk failed". My sister ran diagnostics on it and it comes back saying that the hard drive passed. But nothing about the dvd/cd player. Would it not pick that up? It is part of the computer. My question is: Now that the hard drive has passed, and its not reading the Windows 8 disk, is it a dvd/cd problem, or is it some thing totally different? My sister and my dad have money issues right now and can't afford to use an HP tech. So I'm hoping that someone knows what could be wrong and what I may be able to try.
Thank you so very much,
Andrea K.

Hello liv2lrn,
This is bad news especially around Christmas time. Your fathers computer is not worth fixing. Motherboard is corrupted, because these steps given faild. It is cheeper to buy another computer then it is replacing a motherboard. That's even if HP has one in stock. What I would do is shop on E-Bay you can find real good deals there for another good used one. I puchased a high value Sony VGC-LLT25E 24" screen computer for $300.00 Amazon at the time had two listed for $1999.00 and the other one at $1800.00 both were sold with in two weeks. I got lucky . That computer has out lasted three HP computers witch are newer. It is in mint condition runs a whole lot better then my HP's computers do. Shop wisely. You can save lots of money like I did.
Good Luck I am sure you can find a real good deal like I did.
frrw.

I broke my iPhone 4s screen, i gave it for repairing & before i gave it for repairing my wifi was working totally fine & now all of sudden my iPhone cant detect any wifi, it would only detect if iPhone is placed beside router! Is it hardware prob?

If yes than the repairer wont take the responsibility & is denying that it is hardware problem! what should i do?

Pursue the matter with whoever repaired your iPhone. When you had
an unauthorized service open your iPhone, you voided your warranty.
Most likely the repair knocked something else loose in the iPhone or otherwise
damaged the hardware.

Solaris 8 boot disk...

I have been having problems trying to install Solaris 8 to a PC. I keep getting the error "can't open - no VTOC" when booting with the CD and people have been suggesting I need to use the Solaris fdisk and format tools but I cant find a boot disk anywhere on the CD or the web site. Can anyone tell me where to download one or maybe email me one???
Getting frustrated in Ohio,
Thanks a million

Hi,
You can download the DCA diskette from the web site:
http://soldc.sun.com/support/drivers/dca_diskettes/#s8
You would find all the releases of Solaris. You can check the integriry of the CD which you have burnt by mounting it on another Solaris machine(if you have any). You can try booting from the cd 1 of 2 after you have created a small dos partition and made it active.
Hope that helps.

Cant see the boot drive when installing, what to do?

Trying to install windows 7 on my MacBookPro 15” late 2013
Using a SDcard and Boot disk
Using Bootcamp Setup Assistant to create a partition and a boot disk via a 64 Win7 installer ISO file
Everything looks fine, it copys everything to the SDCard, formats it to Fat, copying drivers and all, reboots but when the install screen comes up, it says that it cant find any bootable disk
Have done it three times now; with different ISOs, but cant get it to see the installer, any tricks?
Thanks

One option is to download the drivers on the SDCard and just put the Windows ISO on the 4GB USB. If you are installing Windows 8.I have two separate disks of roughly 4GB each for 32-bit and 64-bit. I have created iso from the 64-bit disk on my desktop and can have Bootcamp drivers (~950MB) and the ISO fit on a 4GB USB.
Also, after Windows install, you have read-only access to the OSX HFS+ partition, so you can copy Bootcamp drivers directly from the OSX side to the Windows Documents folder and install Bootcamp drivers, without needing the SDCard.

Boot disk Vista Home required after new HDD was placed!

Anyone that knows what to do now? I never received any discs with my Laptop (legal purchase). I have windows Vista Home on my laptop?
Anyone had the same problem and has it sorted? Will any boot disk download work?
Does anyone have a good tip? Thankyou.

Hello
All new Toshiba notebooks are delivered WITHOUT installations discs and you must create such disc alone using preinstalled "Toshiba Recovery Disc Creator". the shortcut of this application is placed on the desktop.
When you buy new notebook and start to use preinstalled operating system small recovery disc reminder with follow content should be shown:
*+Important INFORMATION+*
*+your system is equipped with hard disk recovery system. If you need to repair your computer by restoring it to original factory state, you can do it directly+*
*+from harddisk (press F8 when you boot your computer, choose "Repair your computer" and follow the menue instructions) or create a bootable Recovery Disc Medium for this purpose.+*
*+Toshiba recommends you to create Recovery Disc Medium using the "Toshiba Recovery Disc Creator" to ensure that you are able to restore your computer to the original factory installed state, even if your computer gets seriously damaged.+*
So please create recovery DVD using empty DVD-R medias. I presume you need 2 of them.

How can I get a boot-disk for a Compaq P2500 laptop Windows XP Home Edition?

I'm already in another forum with a eerily similar question, but that's for the HP Media Center Pavilion m8000e desktop system (Windows Vista Home Premium) I was just given; I've ordered a new hard drive for that. I assume the directions to create a boot disk with the *.iso file (using Imgburn) is going to work; I have the 25-digit code for that.
This question here now is for my wife's older Compaq P2500 2596US laptop running Windows XP Home Edition. This too needs a new hard drive, but I also am missing the boot disc for this; I do have the 25-digit product code.
How can I get a boot disk for this laptop? I tried the Ubuntu method outlined in a few posts; geez, what a headache ... never could get it managed. Does HP not make any boot disks available? Microsoft told me to check with HP.
I can furnish the product code; model #; serial# ... gee, maybe the oroginal receipt is even laying around somewhere ...
I need a boot disk to get the new hard drive up on board (if I end up ordering that).
Thanks for any help!
Michael

JMF cant detect more than one camera

hiiii to all
1 ) in my program that list all devices (webcams) connected to my DELL laptop ( windows xp2 ) and choose one to capture from
it detects only one cam that is embeded in my lap when i connected another cam
it lists only the embeded cam and not detect the external connected cam although i capture from it with my program on other pc
i tried also JMF registry to detect capture devices it also detect the embeded cam only
2 ) also i tried to run the program on another HP laptop (windows vista business) and cant detect any devices(audio,video)
Is JMF conflict with widows vista?
really need answer for these 2 questions
thanks in advance

I'll answer your first round of Flex questions, but they are off-topic for this forum because they have nothing to do with Java...but I'll answer these for you.
how about adobe flex? is it possible with desktop applications using socket programming ?
or it is used on web pages only ?Flex is a web-based or Desktop application architecture...
and how about its capabilities ? easy to use or not ?Dunno, never used it. The code I saw looked pretty simple, it uses something called "ActionScript" to function, which looks a lot like JavaScript.
When I looked into it, I never had any doubt that I'd be able to write an application in it.
can i use both JMF, Adobe flex in same application efficiently ?No, they are completely different things, you can't mix them into the same application. It's certainly possible to transmit data back and forth between a Flex application and a JMF application, but they would be separate applications.
If you have any other questions about Flex, you'll need to find an Adobe Flex forum to ask them in...

My iMac cannot detect the Hard Disk

Hi, i've got a question...
Something is wrong with my new iMac. Somedays (only somedays) my iMac cannot detect the hard disk, so when I startup it stops on the initial screen (whit a gray "apple" and background). I tryed to startup it with OSX system discs but the installation app and disk utility don't detect any Hard Disk.
At an authorized store have said to me that can be a software problem...
Is that true? I thought that was a hardware problem.
Thanx,
Eneko
iMac 17"/2.0GHz Intel Core 2 Duo/1GB 667 DDR2 SDRAM/160GB Serial ATA Mac OS X (10.4.8)

Given the young age of you machine I believe you should be taking Apple to task on this one. I'd advise you back-up your data to multiple locations before you go any further.

How can I reinstall crashed iCal without the Boot Disks?

I crashed iCal the other day by adding too much text into the event details field. How do I fix the program, or how do I re-install a fresh version of it? I have a MacBook Pro OS X 10.7.3
I also don't have any boot disks for the operating system (which is what the internet suggested using to re-install iCal off of).
Here is the error message I got:
>> The server responded with an error.
[Then with the text that I was trying to add underneith it]
The text reaches past the screen, and I can't move the window to see what it says at the bottom.

Greetings,
This doesn't sound like an error with the iCal application but with the data you have in it.
Lion (10.7) does not come on a disk. It is available via download (if you purchased it in the Mac App Store or if your computer came with Lion preinstalled) or as a USB thumbdrive you buy from Apple.
For this issue I would suggest:
Quit iCal
Click anywhere on the desktop and then click on the "Go" menu at the top of the computer screen while holding down the "option" key on the keyboard. You will see "Library" in the menu. Click on it.
Click once on the folder called "Calendars" to highlight it.
Go to File > Duplicate (this makes a backup as you can't use iCal currently).
Once the duplication is complete, remove the following to the trash and restart your computer:
Home > Library > Caches > com.apple.ical
Home > Library > Calendars > Calendar Cache, Cache, Cache 1, 2, 3, etc. (Do not remove Sync Cache or Theme Cache if present)NOTE: To get to "Home > Library" in Lion: Click anywhere on the desktop and then click on the "Go" menu at the top of the computer screen while holding down the "option" key on the keyboard. You will see "Library" in the menu.
Launch iCal and test.
If the issue persists:
1. Go to iCal > Quit iCal
2. Remove the following to the trash and restart your computer:
Home > Library > Caches > com.apple.ical
Home > Library > Calendars > Calendar Cache, Cache, Cache 1, 2, 3, etc. (Do not remove Sync Cache or Theme Cache if present)
Home > Library > Preferences > com.apple.ical (There may be more than one of these. Remove them all.)
--- NOTE: Removing these files may remove any shared (CalDAV) calendars you may have access to. You will have to re-add those calendars to iCal > Preferences > Accounts.
3. Launch iCal and test.
Hope that helps.

HP Pavilion g6-2330dx. "No Boot Device. Insert boot disk and press any key" Memory test failed

Hi. So I am trying to help a friend with her laptop. It's a HP Pavilion g6-2330dx.
Product #: D1C01UA#ABA
Serial #: [Personal Information Removed]
Windows 8
ADATA 4GB RAM
Toshiba 640GB HDD from the looks of it.
The laptop is unable to boot into Windows, so I suspect the hard drive. But I ran the hard drive test and it passed all the tests. The SMART test and both the short and long test. I ran the tests multiple times and it passed each time. I tried reseating the hard drive and still no go. I also removed the HDD and connected it to my desktop PC to see if it detects and it did. Ran the Windows 7 own HDD test and it passed.
Currently, there doesnt seem to be any operating system at all on the HDD. When I check, there is a C: drive of ~90GB partition that is ~90GB free, but inside there are Windows files/folders. There is also a D: drive Recovery partition that says ~26GB with only ~2GB free, but when I go inside there's only ~350MB worth of data.
So then I ran the memory test (in BIOS) and it failed immediately. I reseated the RAM module. I tried the other slot. It still failed. So is it safe to say the memory is the cause of this problem?
Pressing the F11 key that is supposed to take me to the System Recovery only leads me back to the black screen with "No Boot Device. Insert boot disk and press any key"
I even tried to install Windows 7 to see if it'll work. I was able to get the laptop to boot/read off the Windows 7. But when I click to install, it asks for a boot device driver or something like that.
My friend doesn't have the recovery disk either. I guess she lost it.
Anyway, is it as simple as replacing the memory or could it actually be the HDD (even though it passes)?
EDIT: This is what the System Log in BIOS says
0021           Time: 10/13/2014
03F0           Time: 10/13/2014
03F0           Time: 10/13/2014
The date was the first time I ran the tests. I havent received those numbers (error codes?) since.
EDIT: Just for kicks, I ran Memtest 2.11 just now (forgot I had the disc) and it immediately went red with thousands of errors, hah.

Hi bghs,
Welcome to the HP Forums!
It is a fantastic place to find answers and information.
For you to have the best experience in the HP forum I would like to direct your attention to the HP Forums Guide Learn How to Post and More
I understand that you were unable to boot into Windows, and you suspected the hard drive and tested it, but it passed both short and long test. With that being said and the fact that it also passed leads me to believe the hard drive is fine.
You tested the memory and it failed. You tried reseating and swapping slots but they still failed the test.
I would test each card individual with the memtest to determine if it is just one or both cards that have an issue.
When you installed it in another computer, you did see the recovery partition. Once the memory issue is resolved, if you are still unable to boot into Windows, I suggest you do a recovery with the minimized image.   Here is a link to Performing an HP System Recovery (Windows 8) to assist you with that process.
I hope this helps.
