Can't figure out what is wrong with recovery DVDs
Last year, right after turning my laptop ON, I've created 4 DVDs as such: http://i56.tinypic.com/6i79rn.jpg
Recovery DVD Disk 1
Recovery DVD Disk 2
Recovery DVD Disk 3
Windows Recovery Environment 64-bit
My Laptop is Qosmio F60-14R, with Windows 7 Home Premium.
Now all I want to do is format my laptop and re-install windows 7 Home premium using those 4 DVDs. However I can't figure out why I cannot re-install or get the laptop back to the factory state.
This have wasted 8 hours straight of my time and frustrated me by great deal. Can you kindly tell me what I have to do? I am lost!
Here is what I have done so far:
I inserted 'Windows Recovery Environment (64-bit)' DVD and booted the laptop from it.
First thing that loads up is a window with two options:
- Toshiba Recovery Wizard
- System Recovery Options
Taking Toshiba Recovery Wizard as choice, clicking Next.
It asks me: "Please set 1st Recovery Media and press Next to Continue.
So, I insert Recovery DVD 1 and then click Next. However it ejects the disc drive (seems Recovery DVD 1 is not the correct Disk!).
So I repeat the same process with Recovery DVD 2 and Recovery DVD 3 and again the Disk Drive ejects the Disks.... As a desperation attempt I even put the Windows Recovery Environment Disk inside but that as well get ejected.
Okay, so the Toshiba Recovery Wizard is not the right choice 'it seems'.
So, I restart the laptop and inserted 'Windows Recovery Environment (64-bit)' DVD and booted the laptop from it.
First thing that loads up is a window with two options: (First choice failed, now trying second choice)
- --Toshiba Recovery Wizard--
- System Recovery Options
So, choosing System Recovery Options this time and clicking Next. I Choose US as Keyboard, then click Next. A small window appears which gives me two further options:
- Use Recovery tools that can help fix problems starting Windows. Select an Operating System to repair.
- Restore your computer using a system image that you created earlier.
So, I already tried the first choice and it takes me to another window with several recovery tools. One of the tools is System Image Recovery but when I click it, it gives a Warning messagebox that says:
Windows cannot find a system image on this computer. etc.
But when I insert every disk, still the warning messagebox shows up as if all the four recovery DVDs are irrelevant.
So, it seems the first choice doesn't lead me anywhere. So, remains the second choice:
- Restore your computer using a system image that you created earlier.
Turns out it is exactly the same 'System Image Recovery' from first option mentioned few lines earlier. So, there you have it, checkmate.
Please guide.

Trouble with calculating fields. Can't select (check) fields. Also can't figure out what's wrong with a division field (percent) that I created. Keep getting the pop up that format of the field doesn't allow blah blah blah... Help!
1. Use the mouse to select the field and then press the space bar.

I can't figure out what's wrong with this code
First i want this program to allow me to enter a number with the EasyReader class and depending on the number entered it will show that specific line of this peom:
One two buckle your shoe
Three four shut the door
Five six pick up sticks
Seven eight lay them straight
Nine ten this is the end.
The error message i got was an illegal start of expression. I can't figure out why it is giving me this error because i have if (n = 1) || (n = 2) statements. My code is:
public class PoemSeventeen
public static void main(String[] args)
EasyReader console = new EasyReader();
System.out.println("Enter a number for the poem (0 to quit): ");
int n = console.readInt();
if (n = 1) || (n = 2)
System.out.println("One, two, buckle your shoe");
else if (n = 3) || (n = 4)
System.out.println("Three, four, shut the door");
else if (n = 5) || (n = 6)
System.out.println("Five, six, pick up sticks");
else if (n = 7) || (n = 8)
System.out.println("Seven, eight, lay them straight");
else if (n = 9) || (n = 10)
System.out.println("Nine, ten, this is the end");
else if (n = 0)
System.out.println("You may exit now");
else
System.out.println("Put in a number between 0 and 10");
I messed around with a few other thing because i had some weird errors before but now i have narrowed it down to just this 1 error.

For the past few months, my Mac has been acting weird. EVERY time I boot up the computer, Messages opens automaticallly (I am runing OS X 10.8.x). I quit the app, but it just re-opens a few seconds later! It just won't stay off! I've looked it up online and nothing helps. I have no idea what to do!!!
Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up guest users” (without the quotes) in the search box. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode.
Test while in safe mode. Same problem?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2. -
Can't figure out what's wrong with my code
Hello everyone. I'm new here and I am trying to write this program and am completely stuck. What i want the program to do is to read in two directory paths from the user and compare those directories and print out the differences. The catch is i only want it to compare 2 directories deep. For example, to compare the music folder on my hard drive and on my external hard drive. My folders are organized: my music>artist>albums, so i just want it to be able to search these folders, not the files inside the albums folders, to show what's different. I hope that makes sense... Anyways, here is the class that I have written to do the comparison. The error it is giving me is:
Exception in thread "main" java.lang.NullPointerException

Can't figure out what is wrong with my form
Aloha all!
Need some help from my DW friends. For some reason my form isn't emailing all the fields. I have sent several tests and only 2 of the fields are showing, the name and the comments. I can't see why the other wouldn't be working, it looks right to me. Can anyone see what the issue is?
http://www.windwardmassage.com/evaluation.html
Mahalo!!It's because most of your fields have the same name (textfield). Give each field a unique name (no spaces or special characters).

I need help figuring out what is wrong with my Macbook Pro
I have a mid 2012 Macbook Pro with OS X Mavericks on it and for the past few weeks it has running VERY SLOW! I have no idea what is wrong with it, i have read other discussion forums trying to figure it out on my own. So far i have had no luck in fixing the slowness. When i open applications the icon will bounce in dock forever before opening and then my computer will freeze with the little rainbow wheel circling and circling for a few minutes... and if i try to browse websites it take forever for them to load or youtube will just stop working for me. Everything i do, no matter what i click, the rainbow wheel will pop up! The only thing i can think of messing it up was a friend of mine plugging in a flash drive a few weeks ago to take some videos and imovie to put on his Macbook Pro, he has said his laptop has been running fine though... so idk if that was the problem. Anyways, could someone please help me try something? Thank you!!

Master page size conflict? Can't figure out what's wrong...
Hi community,
I posted this ticket earlier, but I think I should post it in English, for a larger audience...
So here's the story :
I got a really odd issue while moving (or adding) pages...
Here's a very basic layout :
Now, lets place page 2 after page 3. Here's the result :
As you can see, pages don't seem to relate properly to master pages.
I can't figure out why...
If I apply masters onto my pages, InDesign says there's a size conflict.
Assuming I would apply again my master, ID will replace elements at the right place for now, but doesn't solve the problem at all.
Any idea ??
Here's a download link for this document :
http://dl.free.fr/lPfXwwajm
Please note, I'm working with InDesign CS6 (8.0.2 version)
Thanks a lot for your help!
VincentHi Willy.
I didn't use the page tool (I never do), but it's a collaborative project, so I can't be sure nobody did.
As you might have guessed, the attached Indd file is not the real file: I did remove all styles, variants, blocks,... everything from the original project to reduce it to a very basic template...
If I create a document from scratch, obviously there is no problem. If I don't find the solution, I will recreate the document from scratch, but you'll understand I'd like to avoid spending my time that way...
So...
I tried changing the orientation from document setup and crtl-z... didn't do the trick!
Now, here are more information for a better understanding:
The original project was landscape orientated (A4).
I had to adapt it to a portrait orientation version (still A4). Please note I didn't use the page tool. Obviously, something got wrong there and did create the problem...
Now, if I right-click my page panel and set its view "by variant", the name of the (unique) variant is the same than the original project, even though it has a different orientation.
The strange thing is that the name is a personalized one (it should have been "A4 H"). Why is that? I dunno... Why (anf who did?) change the name of the "variant" is a mystery... But I guess this could be a clue...
Well... still stuck on this puzzler...
Thanks all for your help anyway... -
I have been having problems with my Macbook ever since I had it in for service to replace the battery. The issue is when I am surfing the page disappears and goes back to the desk top, and I have to reload it again. This happens quite often while I am online, and is a definite glitch.
Please help.

Need help figuring out what's wrong with my code!
I am having a few problems with my code and can't see what I've done wrong. Here are my issues:
#1. My program is not displaying the answers to my calculations in the table.

2a. First, it works correctly for the first 24 lines, but then jumps to every 48 lines.
2b. The line count is supposed to go 24, 48, etc...but the code is going from 24 to 74 to 124 ... that is NOT right!

My phone randomly shuts off. I will be in the middle of using it and it will completely turn off. I can also not have used it all night and I will pick it up and click the home button and then it will flash the apple restart screen. I'm not sure what is causing this as I have only had the phone for about two weeks. It's a little concerning and just wanted to see if anyone knew what it could be without me having to go into the Apple store.
Thanks!Try This...

Please help me figure out what's wrong with my girls fairly new Toshiba lap top.
OK as of late my girl got a nice new laptop. It started off really fast and she was really happy with it. But in the past three weeks or so it's been acting up. It's not connecting to the Wi-Fi properly, and won't read and other available confections. If we reset and restart it one of two times that usually does the trick but the last time took 3 restarts before connecting to the right the way it was made to. To top it all off though. We were just laying down and she had heard the cooling fan going in it. This is odd because I had used it last and i always meme site to shut it down properly. But to my dismay when she picked it up and showed me I could clearly tell it was the cooling fan and that the lights on the side indicated that it was still on. What would cause these things to happen like this and more importantly, what can I do to not only fix the issues, but to stop this from becoming potentialy a bigger and worse problem? Please, anyone with any knowledge on this matter. Please help me out to prevent this from becoming a bigger more expensive issue. Thank you everyone for your time and you only would be greatly appreciated. The model number for this lasso to is XXXXXXXXX. Again thank you

Calling all java gurus - i cant figure out what is wrong with my code
please can someone see why a null pointer exception is being thrown and how do i fix it?
my current code which throws the null pointer is as below - the key issues that i need some java expert to tell me about is
1. is the usage of resultSet ok in the way i'm doing it , i'm not able to look at the code in debug mode as don't have an IDE and don't know how to do a log4j setup. - i tried doing an out.println("Got........"); but servlet keeps on forwarding the request object to results.jsp even when i comment out the code. and recomplie and restart tomcat 4.1.
2. is the way i'm declaring the List object and the adding stuff to bean and then stuffing bean into list ok?
3. why is the List object null? although i know the query works fine - and that using the below original code where only one row of data was being retrieved and set into bean worked fine.
current code with problem in the List object:

<% List myAbridgments = (List) request.getAttribute("results");

abridgment = (Abridgment) myAbridgments.get(i);

Can't work out what is wrong with my nano
The 4th gen Ipod nano isn't recognised by itunes and doesn't turn on, when I try to turn it on it comes up with an hour glass and doesn't do anything else.I have tried reseting it and charging it overnight but I can't work it out. I bought it off ebay so I'm worried it could be fake as I havn't heard of a hourglass coming up on an Ipod and I cant find it when I search it on google.
Does this happen to 'real' ipods?
ThanksHi Carnageboy
Check the back of your iPod and you should see the serial number under the capacity label (it will be tiny text)
Enter the iPod's SN into Apples Warranty checker to see if there is any warranty left:

If there warranty, then call Apple for support.
